Implement pressing Escape to clear text selection in LineEdit and TextEdit

[ZachIsAGardner]

Describe the project you are working on

Just messing around in Godot 3.X and 4.0 alpha.

Describe the problem or limitation you are having in your project

I'm used to being able to press Escape to clear my current selection in a code editor.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Having a configurable shortcut for clearing the current selection would be helpful.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

This is something that could be added as it's own shortcut in the Script Text Editor category. Or it could be hooked into the existing ui_cancel shortcut. This would be similar to Evaluate Selection, it just wouldn't move the cursor around.

If this enhancement will not be used often, can it be worked around with a few lines of script?

I'm not sure.

Is there a reason why this should be core and not an add-on in the asset library?

I think most people would appreciate this.

This needs to be implemented in LineEdit and TextEdit in general, so that non-game applications using Godot can have this behavior out of the box. We may need to add a property to disable this behavior on a per-node basis, as it's sometimes undesired. For instance, Visual Studio Code supports pressing Escape to unselect all text, and so do web browsers in <input> and <textarea> fields. However, Firefox's address bar does not deselect text when pressing Escape.

The script editor (which uses CodeEdit under the hood) will automatically benefit from this as a result.

• In TextEdit, implemented as ui_text_clear_carets_and_selection in Unified shortcut to clear carets and selections from TextEdit godot#68170
• In LineEdit, pressing Escape (ui_cancel) unfocuses it which deselects text in Unfocus LineEdit when pressing Escape godot#81128

Closing, as this proposal is implemented since 4.2 as per the above comment. I've tested it in the script editor and it works too.
