The xev output for both left alt and right alt is given below. I could not use right alt for any purpose due to this. What could be the problem? Thanks in advance.

Yes, it depends on the layout. For example, I use the “English (Macintosh)” variant of the US layout. It has bindings for level 3 shift on all keys pretty much.
I also now set it to macintosh variant. But can I assign it to right shift instead of alt? I need the alt but there seems to be no option for using shift
It doesn’t seem to be available as part of the standard modifiers. You can probably have it as part of a custom layout, but I have no idea about how to do that.
As far as I understand those selectors work, using
shiftas the level 3 modifier is a bad idea since …SHIFT+ keyL3+ keySHIFT+L3+ keyL5+ keyL5+SHIFT+ keyI suppose customizing the keyboard layout such that
SHIFTcan be used as L3 modifier can be done. Otherwise, you might want to refer to/usr/share/X11/xkb/rules/evdev.lst.Here’s the relevant part(s):
