Keyboard shortcut non effective

#1

I recently installed TeXmacs on my new computer Asus VivoBook.
Impossible to obtain \sqrt with the shortcut Alt+s.
What can I do ?
Thank you for help !

#2

Are other shortcut working? Is Alt+S working in other software? One possibility is that the key combination has been intercepted by the OS. Maybe you can disable this in some system setting.

#3

Other shortcuts seem working perfectly : Alt+$, Alt+&, Alt+f are all correct.

I’m afraid it’s my new computer that has a mechanical problem with its keyboard. But a computer repairman told me that if the “alt” and “s” keys worked separately, the keyboard was not to blame.
The fact is that I waste time typing \sqrt instead of alt+s in my many texts to write (I am a volunteer teacher).
Thank you for your kind help !

My computer works with Fedora Linux 37 KDE. I tried also PCLinuxOS in two ways : Live DVD, and virtualized with VirtualBox. The result is the same : the shortcut Alt+s don’t work either.
I think that my keyboard, even “brand-new”, has a mechanical problem.
How to create a new shortcut in TeXmacs (even different from Alt+s), then ?

#5

I would try a program that shows the keyboard input (I used Screenkey on Ubuntu which seems nice).

#6

TeXmacs and this shortcut (Alt+s) work well with Gnome and XFCE.
With Fedora 37 KDE or PCLinuxOS KDE, same malfunction.
I don’t understand why.
Thanks for your lights !

It is possible then that KDE is intercepting Alt s as a system shortcut. This pages seems to indicate there might be such a shortcut:
https://docs.kde.org/trunk5/en/khelpcenter/fundamentals/kbd.html

Try to disable that shortcut in KDE’s settings. If that doesn’t work, you can try TeXmacs’ alternative shortcut for square root: Esc Esc s
