I use ctrl-backspace in MATLAB Editor (MATLAB 2015a) to remove the previous word, but it doesn't work in the command window. I tried changing it in Preferences -> Keyboard -> Shortcuts, but there doesn't seem to be the option to bind it to "Remove Previous Word" in the Command Window. In the attached image, you can see that it is set to work in the MATLAB Editor, but when clicking the down-arrow next to where it says MATLAB Editor, it does not show any other options.
This seems like a very common shortcut used by many Windows programs, and it's strange that it should only be allowed in the editor. If it's actually not allowed, why? Is there a workaround?
I tried to post an image of this but stack overflow says I'm not yet cool enough.

As shown in this screenshot there are 5 occurrences of the "Find" field. But hitting CMD-ENTER -as shown in the shortcut balloon help - does nothing.
Why is it not working/ what can be done to get it to to work? I detest using the mouse for extremely common operations especially Find/Replace.
It is a little odd that the binding is Cmd+Enter on the Mac, whereas it is Ctrl+Alt+Enter on Windows? Things to try:
The equivalent of Ctrl+Alt+Enter on the Mac (and you indicated that Cmd+Option+Enter does work).
Check in the Gear Icon/KeyboardShortcuts editor what the command editor.actions.replaceAll is bound to.
Check in the Keyboard Shortcuts (click on the little keyboard icon to the right and type Cmd+Enter) to see if it is bound to something besides editor.actions.replaceAll.
You can run the Developer: Toggle Keyboard Shortcuts Troubleshooting command from the Command Palette, type Cmd+Enter and see what command vscode finds for that keybinding.
You indicated that Cmd+Option+Enter does work as you expect.
Sometimes when closing vscode, or a tab therein, I get a dialogue asking "Do you want to save the changes you made to filename?" However, the unsaved edits are actually from a previous session that was closed without such a query, probably when turning off the computer, so I can't remember if it was meaningful edits, or maybe just an accidental key-press, like a shortcut gone wrong; and doing undo to revisit the last edits doesn't work either.
My question: How can I see the diff between the saved version of a file, and the version in the editor window? I think it would be nicest just to have a "show diff" option in the dialogue, but for now I'm also happy with a command line diff command.
I'm using ubuntu 20.04.
I'm using VSCode version 1.52.1 on MacOS and I had a similar problem that may not be the same problem, but I'm guessing it will work for you as well.
When you're in the Explorer view, in the upper left part of Explorer you have your "Open Editors." If that shows a dot to the left indicating that the buffer has changes in it, you can right click the file name and select "Compare with Saved." This will open another buffer to the side that will show you any unsaved changes.
To get rid of that window (it took me a bit to figure this out I'm sorry to say!), you can click the 'X' to the left of the extra buffer in "Open Editors."
Hope this works for you!
A few bright notes for the keyboard players out there:
The command you are asking about has a default shortcut. Unless you've applied a keyboard map extension, the Ctrl+Kd arpeggio opens the very same diff view between the active and saved versions of the current file. The default shortcut to close an editor tab (be it the diff or a file or anything at all) is Ctrl+W.
The command, like any command in VSCode, is also accessible via the Ctrl+Shift+P command dropdown (on Linux, F1 opens it too). Start typing e.g. compa sav (it saves your keyboard wear and tear to shorten words to a prefix which is unambiguous enough), and the list will shrink dynamically to just a few commands. Yours is File: Compare Active File with Saved. When it's close to the top enough, navigate the list of commands with the down arrow and execute it with Enter. As a bonus, you may click on the little gear to the right of the command currently highlighted in the list and redefine its shortcut, if you use it very often and prefer a chord shortcut to the default arpeggio one. Sorry, there does not seem to be a shortcut in lieu of the gear click. If there is, please let me know!
But if you really, really want to right-click on the filename in the Open Editors view of the Explorer sidebar, you can open that view directly with, you guessed it, a shortcut: Ctrl+Ke. And if you change your mind on a dime right at this moment, or realize that you in fact never had a mouse to do the right-click in the first place, use Shift+F10 to drop down the "right-click menu", properly called the context menu, which you navigate with arrows and execute with Enter (that's kinda a common theme, as you probably noticed). This works mostly anywhere the right-click does.
While in the Open Editors view, to switch to an editor file tab, move the selection to the desired file. Press Space to bring the file into view but stay in the Open Editors view, or Enter to bring the file into view and shift the keyboard focus to it. Pressing Ctrl+Shift+E brings focus back to the editor from any view in the Explorer sidebar. The same shortcut moves focus to the Explorer sidebar from the editor.
Happy ♬ k'boarding ♬!
ctrl+shift+P (or command+shift+P on mac) and fuzzy search for "compare changes with saved files"
I am having an issue with the Remove Previous Word shortcut in MATLAB.
It works in the editor, but not in the command window. I tried to edit it in the keyboard shortcut preferences page, but you are only allowed to select MATLAB Editor in the Tools with shortcut section, it does not give you the option to add the Command Window.
Does anyone have a workaround for this, or at least know a reason why this wouldn't be implemented for the command window?
I've noticed that Ctrl+Backspace/Option+Delete doesn't delete the word to the left of cursor in the MATLAB editor, as it does in many (most?) other editors and programs. This is intensely annoying, as I often will want to change a function name or small section of code. Currently I am forced to hold shift, use option+left, and then press delete to perform what should be a two keystroke operation.
Is there a way to enable it, or is a similar shortcut available? I found this unanswered question on MATLAB Central, but no further joy.
Edit:
Running R2010a on OSX
Are you on R2010b?
At least on Windows, this is supported starting in R2010b. All the keyboard shortcuts are in File > Preferences, under Keyboard > Shortcuts. Type "word" in the search bar (the text field just above the list of actions) to see the word-level actions. In R2010b, but not earlier versions, there is a "Remove Previous Word" action, and in Windows it's bound by default to Ctrl+Backspace. Sounds like you're using Mac, too; I don't know what the default binding is there.
So, upgrade to R2010b, and maybe adjust the bindings under Keyboard > Shortcuts in Preferences.
This and some other keyboard shortcuts work in the editor but not in the command window. I don't know why. You might want to request that as an enhancement from MathWorks if you want it in the command window, too.
My normal IDE is Visual Studio, but I'm currently doing some development in Eclipse for the first time. If you press Ctrl-X with text selected in either program, it cuts the text and puts on the clipboard exactly as you'd expect. If press Ctrl-X with no text selected in Visual Studio, it cuts the current line. In Eclipse it is ignored. Is there a way to get Eclipse to use Studio's behavior?

I haven't found a way to make Ctrl+X context sensitive, but I did find that you can bind a key to the "Cut Line" command by going to the Window -> Preferences -> General -> Keys dialog. Unfortunately this always cuts the entire line, even when you have only part of it selected. Maybe binding another key to this command will work for you?
