### Godot version

4.0.beta9

### System information

Linux x86_64

### Issue description

The default Next Script / Previous Script shortcuts insert angle brackets into code when switching scripts.
Presumably this affects all "modifier + printable character" shortcuts.

Workaround for next/prev script: change shortcuts to ctrl-pgup and ctrl-pgdn

### Steps to reproduce

Editor Settings > Shortcuts > ensure that Next Script / Previous Script are set to defaults.
Open any script in the script editor.
Press ctrl-shift-comma or ctrl-shift-period.

### Minimal reproduction project
