Its hard to edit text files which this editor, sorry.

Then you are doing something wrong.

Here is a video screen capture of me moving the caret (the vertical typing bar) after the n, after the r, and after the space, and hitting the DELETE key each time (and undo each). All three delete the character to the right of the caret, as they are supposed to.

As a reminder, DELETE deletes the key to the right of the caret; BACKSPACE deletes the character to the left of the caret.

Idea: there is Settings > Preferences > Editing configuration in the section Caret Settings. It defaults to Width: 1, but I am wondering if you have Width: Block After selected instead. If you do that, the caret before the r will look like this:

My first impression of your graphic explanation will seem wierd,

@GerhardKreuzer

Graphic and explanation together seem weird. Pressing DEL should not even delete the n character if indeed the manually drawn black line is the caret. It should be deleting the presumed space between the n and the 0 characters. The Backspace should “delete” the n character.

You say “newest version” but please as @Lycan-Thrope suggests, provide the menu ?=>Debug Info… output.

Cheers.

My first impression of your graphic explanation will seem wierd, but I see numbers with spaces and then the rn close together, suggesting to me, that it may be some kind of code page character I’m unfamiliar with. This is a guess, since I can’t see any debug info that shows your codepage, configuration, plugins, etc., so take that with a grain of salt and bring that information and possibly a ‘real’ screenshot of the behavior so someone more qualified than me can intelligently assist you.
