I find it useful to be able to create an empty new line after current line. End Enter does exactly what I want, but it is not easy to type. Something closer to default keyboard row, like Ctrl+o, would be much better. Can I do this using default Eclipse commands, or is there any plugin providing such functionality?
Shift-Enter inserts a line below the cursor and Ctrl-Shift-Enter inserts above.

I have Googled a lot but cannot find one feature in VScode that I would appreciate greatly:
Copy (or move) rest of the current line (i.e. not the entire line) to the end of next line
Example:
What I have - note the cursor
What I need - again note the cursor
So ideally, with a single keyboard shortcut, I would copy (or move) the remainder of the current line (= "ABC1" in the example) to the end of the next line. Any ideas how to do that? Is it available within VScode, or is there a relevant extension? Thanks!
Since you're asking if there's an extension for it, the vim extensions should at least be mentioned. I have no intention or desire to start an(other) editor war, though.
What you're asking would be trivial in vim (y$, yank to end of line) and there are at least two very popular vim extensions for vscode that will bring the vim keybindings as well as the power of configurable commands and bindings in vim to vscode.
Yes, it would require some effort to learn the "vim way" of doing things, but the upside is that you'll probably never have to re-learn the bindings if you move between editors/IDEs since they are available in pretty much every editor and they make editing very fast and precise.
Drag and drop by mouse
Why are you not using mouse drag and drop text?
Select the text and drag it by mouse where you need
Otherwise, if you have multiple times then you can solve it in two steps.
Step1:
Replace all Name by Name(ctrl+enter)SecretCode
Step2:
Replace all "(ctrl+enter)SecretCode by "
Done
Anyone knows if there is a column editor function in Oracle SQL Developer?
I have to modify the same column in a large number of insert statement and it would be really useful to have a column editor.
To explain better which is my problem i am searching a function similar to Eclipse ones when you type Alt + Shift + A (How do I enable the column selection mode in Eclipse?), and it allow you to edit in one time a lot of columns.
There is something similar or i have to do it manually?
I am using 4.1.5.21 version.
Thanks
If you're using a newer version of Oracle Sql Developer (at least 18.3.x but perhaps before) there is an even easier way.
Simply go to the "Edit" menu and then choose "Block Selection":
Edit/Wrap Selection (enable it):
https://www.thatjeffsmith.com/archive/2012/07/how-to-block-select-text-in-oracle-sql-developer/
Just press Shift and move cursors up and down, etc.
Be careful to press Esc after each edition as it seems to "stick" or something and it keeps adding cursors and modifying where you don't expect it.
Trick: The multi-cursor is useful to edit several parts in the same line.
In eclipse you can hit "enter" and the IDE will automatically take you to the end of the line and place a semicolon.
In IntelliJ, if you hit shift-enter you get similar behavior minus adding the semicolon. I have read and tried cntrl-shift-enter and you get the exact same behavior. However, that is such an awkward key combination to be using all the time, at least much more so than the one-button approach using Eclipse.
Any ideas?
IntelliJ autocomplete escape
In InteiJ IDEA use (Ctrl-Shift-Enter) for "Smart Autocomplete".
It will end the line "smartly" with a semicolon as you wish. It also works in a few different situations like IF statements of FOR loops.
Why don't you redo the key binding?
Go to: (spanner icon) Settings -> Keymap -> Complete Current Statement and rebind how you will (for example, ctrl-enter might suit you better).
Or there's also a default keymap set for Eclipse that you can choose. I'm not sure if it affects the complete-current-line action, but you could take a look.
you can also use ctrl+shift+space
if you want always have it just do this
total Emacs noob here. So right now I'm working on a fairly big LaTeX project in Emacs in which there are couple of places where I need to index some words, using the makeidx package. Because I also wanted indexed words to be bold, I created my own command \ind{} which would make the argument go bold and indexed. But right now I'm dissatisifed with this command so I'd like to change every instance of \ind{whatever} in my text by \textbf{whatever}\index{whatever by default}.
The thing is I know exactly what I want :
Go through the text, look for any instance of \ind{ and replace by \textbf{ using search-and-replace
Save the argument of \ind ("whatever" in this case) in memory
Ask me the user what should the argument of \index be. By default (by striking enter), it should be the first argument, but I can also change my mind and enter something different ("whatever by default" in this case). If there's no input (only a space " " for example) stop the program.
Write down \index{, the new argument and }.
Go to next occurance in the text.
But, alas!, I know not how to achieve this, so I need someone's help. If it should take too much time to explain how to do such a thing, would you please send me some tutorial about writing my own functions?
I hope I'm being clear, and thanks for your patience!
This approach seems vaguely unorthodox to me, but it works and seems sufficient for a one-off job...
In the replacement text for replace-regexp and query-replace-regexp (C-M-%), one newer escape sequence is \,(...), where ... can be any Lisp expression. There's a Lisp function read-from-minibuffer which reads arbitrary text typed by the user, with an optional default. Therefore:
C-M-%: Start query-replace-regexp.
\\ind{\([^}]+?\)}: The pattern to search for.
\\textbf{\1}\\index{\,(read-from-minibuffer "index content? " \1)}: The replacement text. The user will be prompted for the text to put in the braces following the \index{} element, using the original text between the braces following the \ind{} element as a default.
Note that when using query-replace-regexp, you'll have to confirm each choice by typing y after each. Use M-x replace-regexp if you want to avoid this step.
Vlad give you the LaTeX answer to your problem. An Emacs solution is the key-macro: start with
C-x (
to define a new macro, then do one step of your change, say:
C-s \ind{
<left>ex
Then copy and paste the argument in the \textbf macro... You have to be careful to move in a way that will be repeatable. Once the standard modification is done, you let the cursor after the whatever by default and end the definition by
C-x )
now C-x e will call the macro you just define, letting your cursor at the correct place to change the part you want to change You can also repeat the e to call the macro several time at once.
Why not just redefine the \ind so that it can get an optional argument?
For example:
\newcommand{\ind}[2][]{%
\def\first{#1}%
\ifx\first\empty
\textbf{#2}\index{#2}%
\else
\textbf{#2}\index{#1}%
\fi
}
This way you can use \ind{whatever} or \ind[whatever-else]{whatever}.
I'd like to quickly move point to a function in my Emacs buffer. I'd like to run some function and get a prompt asking me for the function name, with completion provided for every function defined in the current buffer.
I generally use etags to navigate around, but sometimes I'm looking for a framework method that's been overridden in several files. In these cases, I can find the file I need but then I'd like to quickly jump to the function there. There is a similar feature in TextMate where you can select a definition from a list in the bottom right of the editor.
Just to jump around functions in the current file? Use imenu. It's the simplest and lightest of all the alternatives listed so far and might be enough for what you want. It's also built into Emacs and has minimum setup hassle. It features graphical and textual interfaces. Anything extra and you'll be better off using one of the other excellent suggestions made here.
speedbar comes standard, and gives you a collapsible menu for each file in the current directory, by default middle clicking on an entry for a function definition jumps to that def. With emacs23 this was changed to the more normal leftclick.
You can use etags-select to select from multiple matching tags. But the answer to what you asked is imenu.
Icicles is probably closer to what you are looking for:
http://www.emacswiki.org/emacs/Icicles_-_Tags_Enhancements
It's an enhancement to etags and includes (among other things) the file name with the tag so you can tell if it's the one you are looking for.
try CEDET. It is a bit difficult to set up the first, but here is an excellent tutorial: by Alex ott
And when he gets installed, you can use semantic-complete-jump. pressed tab couple times, and it is also brings up symbol definitions.
If M-. brings up the wrong method, you can type C-u M-. to find the next one with the same name.
global gtags is very good
To navigate within the current file or a set of files that you select, you do not need a TAGS file. You can use Imenu. But it is better to use Icicles imenu commands.
Why? Because they let you use completion. Substring, regexp, prefix, or fuzzy completion. Combine simple patterns to match, or subtract them.
Command icicle-imenu is bound in Icicle mode to C-c =. Butyou can also look up just a command or just a non-command function (non-interactive), using command icicle-imenu-command or icicle-imenu-non-interactive-function.
These commands are multi-commands, meaning that they are actually browsers: you can trip among function definitions using keys C-RET or C-mouse-2 (direct jumps) and C-down (cycle). Hit RET or click mouse-2 to settle down at a final destination.
I use C-M-a and C-M-e to jump between the beginning and end of functions.
Otherwise, open up Speedbar and click the + icon next to a file name to view a list of functions contained in the file. Then click on the function names to jump to them directly.
