As the title says, in visual studio code you can use the editor.action.joinLines to join different lines of text to one single line? Being an editor noob, the question is how? How do I map this command to a key board short cut, or what mouse actions do I need to do after selecting the said text, to get two different lines as one single line? Specifically I am working on Mac OS X.
To join several lines you have to select them first (you can read more about various ways of selecting text in the vs code documentation) and then invoke the Join Lines command. As a result, all text from the second and next lines will be appended to the end of first lines.
You can invoke the Join Lines command either from the Command Palette by pressing F1 or ⇧+⌘+P on macOS and typing Join Lines or by pressing the assigned shortcut - ⌃+J
You can also configure your own key bindings by clicking File>Preferences>Keyboardshortcuts on Vscode main menu.
There you can bind the command joinLines to your prefered Keyboard keys as shown in this link.

I've recently upgraded PowerShell to version 7.3.0 version and now, when I type a command, I see its suggestions like when I'm typing pip it adds list like in this image. Or when I type start of the command it suggests its full name.
The problem is that when I press Tab it doesn't complete the command, instead it just starts listing current directories, i.e. here is an image after pressing Tab once.
Also even when I start typing the full name of the command like pip li it still shows the ending, but when pressing Tab it just does nothing.
I expected this to complete the current command with the suggestion after Tab is pressed.
I've tried to google this problem but haven't found the exact same case I have with 7.3.0 version.
Just press -> (right arrow) key

Key Bindings for Predictions
Key bindings control cursor movement and additional features within the prediction. To support users running Predictive IntelliSense on multiple platforms, key bindings are user-settable from the command line or your profile script.
PSReadLine contains functions to navigate and accept predictions. As an example, to accept a displayed prediction, PSReadLine contains functions:
AcceptSuggestion – Accept the current inline suggestion
AcceptNextSuggestionWord – Accept the next word of the inline suggestion
AcceptSuggestion is built within ForwardChar, which by default is bound to RightArrow. Pressing RightArrow accepts an inline suggestion when the cursor is at the end of the current line.
AcceptNextSuggestionWord is built within the function ForwardWord, which can be bound with Ctrl+f by Set-PSReadLineKeyHandler -Chord "Ctrl+f" -Function ForwardWord. Pressing Ctrl+f accepts the next word of an inline suggestion when the cursor is at the end of current editing line.
As a user, you can bound other keys to AcceptSuggestion and AcceptNextSuggestionWord for similar functionalities. Search for ForwardCharAndAcceptNextSuggestionWord in SamplePSReadLineProfile.ps1 for an example to make RightArrow accept the next word from inline suggestion, instead of the whole suggestion line.

I am using VSCode on a Mac.
Does anyone know how to select the entire line that the cursor is on? I know about Command+I, but that only selects what appears to be the whole line, which is not always the whole line if I have word wrap enabled.
I am looking for something like Sublime Text's "Expand Selection to Line" command.
All you need to do is put the cursor anywhere on the line, do not make any selection at all and then do the desired command (Cut, copy, or paste).
When no text selected, VS Code will automatically select the entire line.
just triple click the end of the line it will select the entire line
Triple click at any point on the line
Click once on number of the line
Press Command + L
An alternative to what people have posted is, when your cursor is at the start/end of the line, you can hit shift + end/home respectively.
I find this useful for wrapping a line in curly braces/quotes/etc. whereas the other answers include spaces in the select so whatever you're wrapping it in will be wrapped around that whitespace.
Install the MetaGo extension and use the "metaGo: selectLineDown" command, which will come installed already overriding the "expandLineSelection" command.
This extension has many additional commands that you'll likely find useful as well, including moving up/down over code blocks, centering the active line, and going to any character on the screen.
Now, when I press Command+I, the whole line is selected. I am guessing this was caused by an update to VS Code, but I am not sure.
Ctrl + L on Windows or Command + L on Mac to select the whole line in VS Code.
You can use your mouse to select the whole line by triple-clicking on the line but the better way is to click on the line number to select the whole line or multiple lines.
Tripple click at any point on the line
In case you're wondering why Cmd+L is not working, there might be a chance that there are duplicate shortcuts. You can find out by opening Keyboard Shortcuts in VSC and remove the one that's not needed.
I know its old but for anyone seeking, you can press Alt + arrow up/down to duplicate your cursor to other lines and then without selecting anything copy and paste multiple lines.
It happens from time to time that I need to edit 100+ lines in a text file all at once.
I know I can use ⌘ Cmd+↑/↓ to select multiple lines but depending on the size of the file that takes a while.
In Atom and Sublime, I can just do a ⌘ Cmd + a to select everything, hit another shortcut (forgot the actual shortcut) and end up with a cursor for every line.
Have not found this in VSCode.
Ctrl-a to select all. (or whatever muli-line selection you want)
Shift-alt-I will put cursors at end of each selected line.
And then if you want those cursors at the beginning of each line you need to trigger the command "cursorLineStart" which is unbound by default. Give it a keybinding and all those end-of-line cursors will jump to the beginning of each line.
With v1.43 and Column Selection Mode this can be quite easy, see Column selection like Visual Studio and How to put the cursor at the end of all selected lines in Visual Studio Code?
FWIW cursorLineStart is not the opposite of Shift-Alt-I. In looking at the commends, Shift-Alt-I is "Add cursors to line ends", but there is not a "Add cursors to line begins" option.
However, the easy trick for that is:
Select your text block
Shift-Alt-I to put a cursor at the end of each line
Command-LeftArrow will move those cursors to the beginning of the lines
Its an extra step but it works. When I get time I will play around with building a custom command to do all this in one action.
Are there any trick or extension to select all instances of selected word in visual studio code, to facilitate editing or deleting those instances without search and replace, like ِAlt+F3 in sublime text
Select All Occurrences of Find Match editor.action.selectHighlights.
Ctrl+Shift+L
Cmd+Shift+L or Cmd+Ctrl+G on Mac
According to Key Bindings for Visual Studio Code there's:
Ctrl+Shift+L to select all occurrences of current selection
and
Ctrl+F2 to select all occurrences of current word
You can view the currently active keyboard shortcuts in VS Code in the Command Palette (View -> Command Palette) or in the Keyboard Shortcuts editor (File > Preferences > Keyboard Shortcuts).
What if you want to select just a few?
No problem, first:
Ctrl+F find the letters by typing them
ESC to quit searching
(you need to do this even when using
Ctrl+Shift+L
to select all occurences)
OR
just select those letters with your mouse or keyboard
(Shift+arrows)
Now that the mouse cursor is blinking on your first selection,
using a few more Key Bindings (thanks for the ref j08691)
you may:
Ctrl+D select (add) the next occurrence
Ctrl+K+Ctrl+D skip
the current/latest occurrence and add the next occurrence
Ctrl+U undo the latest cursor operation
on Mac:
select all matches: Command + Shift + L
but if you just want to select another match up coming next: Command + D
If you want to do one by one then this is what you can do:
Select a word
Press ctrl + d (in windows).
This will help to select words one by one.
On Ubuntu:
Ctrl + F2 will select all occurrences immediately.
Ctrl + D will select occurrences one by one.
In my MacOS case for some reason Cmd+Shift+L is not working while pressing the short cut on the keyboard (although it work just fine while clicking on this option in menu: Selection -> Select All Occurences). So for me pressing Cmd+FN+F2 did the trick (FN is for enabling "F2" obviously).
Btw, if you forget this shortcut just do right-click on the selection and see "Change All Occurrences" option
Ctrl+Shift+L to select all occurrences of current selection.
Several options have been listed, but a couple are missing. Its possible to use the rename and refactoring tools, for not just selecting all, but making specific changes, after everything has been selected. I am going to try and bundle all answers I feel are relevant together, and add two more that, not only get the job done, but are really great tools for making single changes over multiple occurrences of the same code.
1. Select All Matches
To use multiple cursors to select all matches, you can use 1 of 2 keybindings. Both keybindings preform the same functionality, so in other words, 2 keybindings, 1 vscode command. The keybindings are as follows.
1. CTRL + F2
2. CTRL + SHIFT + L
Default Keybinding
{
"key": "ctrl+f2",
"command": "editor.action.changeAll",
"when": "editorTextFocus && !editorReadonly"
}
// You can view/customize VSCode keybindings by pressing F1 and typing Keybindings
2. Select Next Match
You can Select Next Match by using the keybinding below. This is good for selecting all occurrences within a specific vicinity.
CTRL + D
Default Keybinding
{
"key": "ctrl+d",
"command": "editor.action.addSelectionToNextFindMatch",
"when": "editorFocus"
}
SIDE NOTE
If you press the keybinding CTRL + K before pressing CTRL + D, instead of selecting the next instance, it will move you to the next instance, and target it with your cursor.
Default Keybinding
3. Rename
This one hasn't been mentioned yet, but this one is what you would except when doing a refactor in a traditional IDE, like Visual Studio 2022, or JetBrains: IntelliJ.
When you use this keybinding, it attempts to solve some of the problems that are incurred when using the other options listed above. The other options are overly greedy sometimes, and select parts of words that you didn't want to select, and if your not careful, you can delete quite a bit of code, resulting in messy situation. If you didn't notice that you screwed up right away, you end up saving, or working for a long while before having to reset everything, and you end up loosing a lot of work & time.
F2 attempts to solve this problem by implementing logic under the hood (IDK if its an algorithm or what it is) but it feels very much like refactor in Visual Studio. It only selects specific cases that you would want to target. So if a varable is named foo, is won't select foo from a var named fooFoo. It also won't select foo from a comment.
F2
{
"key": "f2",
"command": "editor.action.rename",
"when": "editorHasRenameProvider && editorTextFocus && !editorReadonly"
}
4. Find
This one I will keep short and sweet, but find will iterate through ever occurrence of a pattern that you type into the editor-widget.
Press CTRL + F then type what you want to select. Keep pressing ENTER until you find it.
5. The Best For Last
There is not one method for selecting all occurrences that is the best every time, that's why there are several different methods for doing it, however, there are some methods that are generally more useful than others. This feature, as far as I know, is unique to VS Code, and I use it all the time when working with large JSON files, and Large Code Bases (like an Open Source PR).
VS Code has its own search editor, its a special editor. You can open the search editor by pressing on the Magnifying Glass Icon on the Activity-bar. Type into the search editors side bar text-input what it is you want to select, then press ENTER. It will return all the results in the sidebar. You can use the lower text input, to replace all of the results with what ever you like. You can also click OPEN IN THE EDITOR (it looks like a link) and it will reproduce everything you searched for in a new document, that is opened to the side. From there you can manipulate it, and add it back to the document. I've already written enough for one answer, so I am not going to go to deep into every thing it can do, but this not only selects everything, it also extracts it, replaces it, lets you nit-pick exactly what it means to select "all" of a specific occurrence. It's a great tool for making a single change in a recursive fashion.
This seems an old question, but it worth an answer.
There is - besides the accepted answer - a fancy shortcut to do this, just select the desired word and press Ctrl + D as many times as desired, each press will select an exact occurrence in the editor, after all occurrences are selected, just type the replacement and all the occurrences will be replaced as you type.
Ctrl + F2 works for me in Windows 10.
Ctrl + Shift + L starts performance logging
I needed to extract all the matched search lines (using regex) in a file
Ctrl+F Open find. Select regex icon and enter search pattern
(optional) Enable select highlights by opening settings and search for selectHighlights (Ctrl+,, selectHighlights)
Ctrl+L Select all search items
Ctrl+C Copy all selected lines
Ctrl+N Open new document
Ctrl+V Paste all searched lines.
I had another application, called Loom, running in the background on my Mac which was taking over my keyboard bindings.
Cmd+Shift+L
It was just random that I figured out it was preventing the keyboard bindings from reaching VS Code. I tried to turn off applications that I had open one by one. Not the best approach, but it worked.
Additionally to unselect use
Cntrl + U
I have a huge code and now for testing purpose I have to add that whole script into an infinite while loop is there any short way (without pressing space for each row) to add a space for indentation so the whole code is consider part of the one while loop ? Such as for example when we press ctrl +r it comments out the line
Ctrl-I/Cmd-I will automatically indent the file. Other wse you just select multiple row and use Tab/Shift-Tab to move them backwards and forwards.
For indentation is a must, however Matlab as a language does not care so it is not really a must to indent it. Additionally, you can just execute the code from the command line, say that you script or function is called Umar, then from the command line you just type while 1, Umar; end.
You can copy the code into notepad++.
Activate Column mode selection holding alt+shift and use the mouse to select the column of all the text you want to insert a space/tabulation/etc. and just insert it.
Final step is to copy back the code to matlab.
Matlab does not currently support column selection.
MATLAB has the option to select all your code, then press the right click and select smart indent button.
If you like to use shortcuts, just type the combination of Ctrl+A (select all) followed by Ctrl+I (smart indent)
