I am looking for a shortcut in eclipse to select which I have already used in IAR Embedded Workbench but I didn't find it in Eclipse.
briefly shortcut explained in Iar's doc and looks like in the gif below:
To select text, press Shift and the corresponding command for moving
the insertion point. In addition, this command is available:
A column-based block: Shift + Alt + Arrow key
Use Alt-Shift-A to start block selection. Then use Shift+arrows to select an aligned column as in your example. Once you use Alt-Shift-A again, the selection mode goes back to normal.
Long-time Arduino IDE user, one-day VS Code + Arduino extension user:
When I first load a sketch and do "Arduino:Initialize", the name of the sketch is stored in the arduino.json settings file, e.g. "sketch": "esp32_test/esp32_test.ino". It then compiles ok when I press the "Verify" button.
But if I close that sketch and open a different one, and then do "Arduino:Initialize", the first file is NOT replaced in the arduino.json file. The first one remains there. I get a message that says, "Arduinio.json is already generated." So when I try to compile the new file, the old one is compiled instead.
The only way I've been able to compile a different file is to manually edit the arduino.json settings file to remove the "sketch": "esp32_test/esp32_test.ino" entry. Then AND ONLY THEN will the .json file update to allow me to compile the new file.
Shouldn't this happen automatically when I select/edit a file and hit the Verify button? Maybe there's an issue with my installation...?
(forgot to mention: VS Code + Arduino on OSX 10.14.6)
Down at the bottom, on the right you'll see the Arduino status bar. There you'll find your board, your programmer, your port... and the .ino file that you're compiling. Click there, change the name to the sketch you want to compile and done!
It's no intuitive.
You should select the sketch in the status bar:
and then you can change the sketch in the upper screen text box:
I know exactly the issue you are having - because it happens to me quite often.
In the status bar, often the sketch file name will not be displayed for some reason - I think this is an issue with the Arduino extension. You'll see everything else you need - board, port, etc, but not the "target sketch"
Here is how you can change the "target sketch":
Open the command pallete (Ctrl + Shift + P for PC - CMD + Shift + P for mac)
Type in "sketch"
Select the option "Arduino: Select Sketch"
Select the sketch you want to upload/verify -> this will now become the active sketch
Like other respondents mentioned, it "should" be shown in the task bar, but for some reason it does not sometimes.
How do I discover Elm's REPL in VS Code?
Specifically, I have no clue how to get up and running with Elm and VS Code.
My past experience involves using F# and Visual Studio.
How do I send instructions to Elm's REPL?
Where is Elm's REPL located within VS Code's IDE?
Any suggestions?
Once you've installed the Elm package, you can use the Elm: REPL - Start command to start a REPL session.
(You access this command the same way as you access other commands in VS Code: by opening the Command Palette. This can be done through the View menu (View -> Command Palette) or with a keyboard shortcut (Ctrl + Shift + P or Cmd + Shift + P, depending on whether you use Windows or Mac).
Once the session has started, you can send lines or selections to the REPL. Type a line into your editor, then run the Elm: REPL - Send Line command to send it to the REPL. There is a default keyboard shortcut for this (Alt + /) as well.
If you want to send more than a line, highlight the thing you'd like to send (probably a function or value definition), and run the Elm: REPL - Send Selection command. Again, there's a keyboard shortcut: Alt + Enter.
Note that the REPL does not support type annotations; sending type annotations to the REPL will result in an error. You can still annotate your function and value definitions in your code, but when you highlight the definitions to send to the REPL, just make sure not to highlight the type annotations.
If you're just looking to play around in the Elm repl, just do this:
1) install Elm globally (using npm, or using an installer from elm-lang.org)
2) open VS Code, then press CTRL + ` (or Cmd + ` on a Mac); this opens VS Code's built-in terminal
3) type elm-repl -- this starts elm's repl, and you can try out snippets, etc
However since your real question is about getting up and running w/ Elm in VS Code, here's a start:
1) download/install elm-format from https://github.com/avh4/elm-format
2) install VS Code
3) install VS Code extension "elm" (it's by a Sascha Brink); add "elm.formatOnSave": true to your VS Code settings
Now when you create/edit a .elm file you'll get code coloring, etc.
If your Elm code is for an app (as opposed to repl snippets), you'll want to see results in elm-reactor. So start a VS Code terminal (see above), type elm-reactor, and your app should be served at http://localhost:8000
In short; You don't want to use vscode (yet) for Elm development. Either go with Atom (Elmjutsu) or IntelliJ (CE works fine with the elm-plugin).
You get support for refactoring and fast navigation. The reason I don't recommend using vscode is because the elm-plugin is underdeveloped.
Unfortunately, the elm-plugin with IntelliJ also is a little underdeveloped, since it does not underline-highlight errors in your sourcecode – so tracking errors does have a cognitive tax.
I know that this question is related to the elm-repl and the possibility to send your selection to the repl is a nice one. But it only saves you two shortcuts (copy selection, send to repl vs copy selection, alt-tab to repl, paste and enter). The way lines are formatted (in elm-format) renders send-single-line as mostly a not-properly-thougth-through feature.
What I do is open a terminal and open elm-repl there, and I split my screen so I always have the output available.
What are the keyboard shortcuts for creating multiple cursors in VS Code?
Press Alt and click. This works on Windows and Linux*, and it should work on Mac, too.
More multi-cursor features are now available in Visual Studio Code 0.2:
Multi cursor improvements
Ctrl+D (Cmd+D on Mac) selects next occurrence of word under cursor or of the current selection
Ctrl+K Ctrl+D moves last added cursor to next occurrence of word under cursor or of the current selection
The commands use matchCase by default. If the find widget is open, then the find widget settings (matchCase / matchWholeWord) will be used for determining the next occurrence
Ctrl+U (Cmd+U on Mac) undoes the last cursor action, so if you added a cursor too many or made a mistake, you can press Ctrl+U (Cmd+U on Mac) to go back to the previous cursor state.
Adding cursor up or down (Ctrl+Alt+Up / Ctrl+Alt+Down) (Cmd+Alt+Up / Cmd+Alt+Down on Mac) now reveals the last added cursor to make it easier to work with multiple cursors on more than 1 viewport height at a time (i.e. select 300 lines and only 80 fit in the viewport).
This makes it a lot easier to introduce multiple cursors
* Linux drag-window conflict:
Some distros (e.g. Ubuntu) assign window dragging to Alt+LeftMouse, which will conflict with VSCode.
So, recent versions of VSCode let you toggle between Alt+LeftMouse and Ctrl+LeftMouse under the Selection menu, as detailed in another answer.
Alternately, you could change your OS key bindings using gsettings as mentioned in another answer.
Multi-word (and multi-line) cursors/selection in VS Code
Multi-word:
Windows / OS X:
Ctrl+Shift+L / ⌘+Shift+L selects all instances of the current highlighted word
Ctrl+D / ⌘+D selects the next instance... and the one after that... etc.
Multi-line:
For multi-line selection, Ctrl+Alt+Down / ⌘+Alt+Shift+Down will extend your selection or cursor position to the next line. Ctrl+Right / ⌘+Right will move to the end of each line, no matter how long. To escape the multi-line selection, hit Esc.
See the VS Code keybindings (OS sensitive)
May 2017
As of version 1.13
Add multiple cursors with Ctrl / Cmd + Click
VSCode developers have introduced a new setting, editor.multiCursorModifier, to change the modifier key for applying multiple cursors to Cmd + Click on macOS and Ctrl + Click on Windows and Linux. This lets users coming from other editors such as Sublime Text or Atom continue to use the keyboard modifier they are familiar with.
The setting can be set to:
ctrl/Cmd - Maps to Ctrl on Windows and Cmd on macOS.
alt - The existing default Alt.
There's also a new menu item Use Ctrl + Click for Multi-Cursor in the Selection menu to quickly toggle this setting.
The Go To Definition and Open Link gestures will also respect this setting and adapt such that they do not conflict. For example, when the setting is ctrl/Cmd, multiple cursors can be added with Ctrl / Cmd + Click, and opening links or going to definition can be invoked with Alt +Click.
With fixing Issue #2106, it is now possible to also remove a cursor by using the same gesture on top of an existing selection.
I had problem with ALT key, fix is to change alt+click as a Gnome hotkey which clobbers multi-cursor select in VSCode, to super+click by running:
gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier "<Super>"
Source: http://2buntu.com/articles/1529/visual-studio-code-comes-to-linux/
Try Ctrl+Alt+Shift+⬇ / ⬆, without mouse, or hold "alt" and click on all the lines you want.
Note: Tested on Windows.
Cmd+Option+Shift⬇ / ⬆ works for me on newest VSCode 1.29.1 and newest OSX High Sierra 10.13.6, Macbook Pro.
This adds a vertical line up/down on screen, like Option+Click/Vertical Drag does in Sublime Text.
To add multiple cursors at any points in your file, including multiple ones on the same line, do Cmd (or Option)+Click anywhere you want, shown in this video. You may also search for text (Cmd+F) that repeats multiple times, then press Option+Return to add cursors at end of EACH word.
On XFCE, go to Applications -> Settings -> Settings editor - > xfwm4 -> easy_click(disable value)
Now you can Insert Cursor with Alt + Click
I've also disabled L/R Workspace (ctrl + alt + L/R) settings in Settings -> Window manager -> Keyboard
As of Visual Studio Code version 0.10.9, you can now do a Create Multiple Cursors from Selected Lines by selecting multiple lines, and pressing Shift+Alt+I
Note: This is similar to Sublime Text's Ctrl+Shift+L functionality.

Relevant PR: https://github.com/Microsoft/vscode/pull/1479
On Ubuntu, in order to enable multi-cursor clicking you will need to re-assign Alt+click first, by running the command below. This is because by default Ubuntu uses the shortcut itself and has it takes precedence.
> gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier "<Super>"
There is no binding for exactly what you want.
The only thing that comes close is Ctrl+F2 which will select all of them at once.
You can bind it to Ctrl+D doing the following:
Click on File > Preferences > Keyboard Shortcuts
You should see a pane full of the current bindings and on the right a list of custom bindings
In the current bindings, search for Ctrl+F2 and copy that whole line and paste it into the right pane.
You might have to remove the comma at the end and then change Ctrl+F2 to Ctrl+D and then save the file.
It should look something like this:
// Place your key bindings in this file to overwrite the defaults
[
{ "key": "ctrl+d", "command": "editor.action.changeAll",
"when": "editorTextFocus" }
]
Ctrl+Alt+⬇ / ⬆ add cursors above and below the current line. Still nowhere near as good as sublime or brackets though. I can't see anything equivalent to Ctrl+D in sublime in the keyboard shortcuts file.
https://code.visualstudio.com/Updates
New version (Visual Studio 0.3.0) support more multi cursor feature.
Multi-cursor
Here's multi-cursor improvements that we've made.
⌘D selects the word at the cursor, or the next occurrence of the current selection.
⌘K ⌘D moves the last added cursor to next occurrence of the current selection.
The two actions pick up the matchCase and matchWholeWord settings of the find widget.
⌘U undoes the last cursor action, so if you added one cursor too many or made a mistake, press ⌘U to return to the previous cursor state.
Insert cursor above (⌥⌘↑) and insert cursor below (⌥⌘↓) now reveals the last added cursor, making it easier to work with multi-cursors spanning more than one screen height (i.e., working with 300 lines while only 80 fit in the screen).
And short cut of select multi cursor change into cmd + d(it's same as Sublime Text. lol)
We can expect that next version supports more convenient feature about multi cursor ;)
Alt+Click. It works in Windows.
Details: Visual Studio Code Documentation
In my XFCE (version 4.12), it's in Settings -> Window Manager Tweaks -> Accessibility.
There's a dropdown field Key used to grab and move windows:, set this to None.
Alt + Click works now in VS Code to add more cursor.
In Visual Studio without mouse: Alt+Shift+{ Arrow }.
You can do the following per the Selection menu:
Press/hold Alt+Ctrl+Up Arrow/Alt+Ctrl+Down Arrow as required to create sufficient cursors, then Ctrl+D can be used to expand the selections.
Same issue on Ubuntu-MATE, but here you resolve it by:
gsettings set org.mate.Marco.general mouse-button-modifier "<Super>"
Alt + Command + Shift will add a cursor to the next instance of what you've selected. E.g. a variable or function name
For xfce users, just go to settings>window manager tweaks>accessibility there change the key used to grab and move windows: to super as demonstrated in the image below.
Now you can use super instead of alt. Wallah!! Go make multiple cursors by alt + click.
First go to "Keyboard Shortcuts", you can get there by hitting Cmd+k then Cmd+s, or for Windows Ctrl+k then Ctrl+s.
Once you're there, search for "Add Cursor Above" and "Add Cursor Below". You can even assign them your own key-bindings.
On windows:
CTRL+Click if you are using vscode
CTRL+Alt+Click if you are using visual studio
For Ubuntu Users
ALT + SHIFT + ⬇ / ⬆
Alt + Click works in OSX. Code Version 1.14.2
This is how it seems to work.
if you don't have any file open, it assumes you're working in the "java mode" and shows the window.
if there's one or more file open, if the focus is on a non-java file (for example, a TCL file) it ignores the key binding if, but if the focus is on a java file, then it works
Since this key binding is used to open a new file, and not to change the current one that has focus, why it considers the current one's type to work or not?
Key bindings have scopes. This helps to use the same keys bindings for multiple commands based on the scopes.
Why it considers the current one's type to work or not?
Because this command is meaningful in this context/scope(i.e If active editor file is of java type).
Click here `Windows > Preferences. Go to General > Keys.
For Ctrl + Shift + T,
Here Ctrl + Shift + T short cut is binded to 3 commands.
If the C file is active then this short cut is consumed by the first command, if C/C++ view is active then by second command etc.
Note that you can change the scope in When selection box and choose the appropriate scope for your need.
