Description Ping 2018-10-06 17:22:46 UTC

SUMMARY
Default Shortcut "Go through the windows of the current application (backwards): ALT+~ " breaks "ALT+4" shortcut in other apps like Firefox or Falkon to change to the tab 4 using a Spanish Keyboard. The num. 4 key and "~" key are the same in a Spanish keyboard. And is impossible for a Spanish keyboard do that combo because to use the "~" symbol we have to press ALTGR+4, then the combination will be ALT+ALTGR+4. 

The weird thing is: In a fresh user account that combo appears, but If y click in reset to default (in the Global shortcuts window) then that shortcut is removed and Is possible to use ALT+4 in the right way.


STEPS TO REPRODUCE
1. Open Firefox or Falkon with 5 tabs and go to the first one.
2. Press ALT+4 to change to the fourth tab.

OBSERVED RESULT
Don't change to the fourth tab.

EXPECTED RESULT
Change to the fourth tab.

I have had this problem since forever (latin american keyboard), today I finally tracked it down to the same cause on my own before noticing this bug report.

Comment 2 Dennis Mayr 2021-06-02 15:24:59 UTC

This behavior is still present on KDE 5.+.

Currently on Kubuntu 20.04, stock keyboard shortcuts:
I checked all assigned defaults, and Alt+4 is unassigned, yet it still doesn't work. Alt+3 and Alt+5 do work, Alt+4 seems to be blocked by some reason.

Comment 3 1jasotel+kde 2022-08-24 14:04:02 UTC

Just wanted to add my 2 cents: I have an up to date (as of 24 Aug 2022) Neon and I have a keyboard with physical UK layout. In KDE I use following layouts: US, DE (german) and ES (spanish). 

I'm also affected by the reported bug. I think just activating the spanish layout is enough to reproduce the problem. Even when said layout is not in use.
