You're welcome, but thank me if/when we get a working solution for you
I was
going to post the following for you a day or so ago, but it did not quite complete. I'll print it anyway and see if you follow.
SUGGESTION STARTS HERE
1. There exists on your Tricia Cinnamon a keyboard remapping function. At the Menu start to type in keyboard, and click on the keyboard entry. When that launches, take a look at
Layouts - Options
and all those right pointing arrows, if clicked reveal more options.
If you choose any of those to experiment be sure you have a current Timeshift screenshot in place first, to roll back if you need to, you don't need a dysfunctional keyboard.
2. If you want some thing more, then there is an update on Github of a utility called Key Mapper, released 3 days ago.
It is GUI point and click.
If you wish to download it and try it, go to
https://www.linuxuprising.com/2020/12/remap-keyboard-and-mouse-buttons-on.html
The releases page is at
https://github.com/sezanzeb/key-mapper/releases
It's version 0.6.0 and you go down to Assets 3 and click the file saying
key-mapper-0.6.0.deb
that will download likely to your Downloads folder.
Once that is finished, you can install Key Mapper either from Terminal (Ctrl-Alt-t is the shortcut or choose it from your Menu) or via GUI point and click, which is graphically from your Desktop.
DESKTOP WAY (GUI - Graphical User Interface ie point and click)
1. Go to Menu and type in software and choose Software Manager.
2. In Software Manager in the search filed type in gdebi and choose to install the first entry.
3. Open your File Manager (called Nemo in Cinnamon) and navigate to where the Key Mapper .deb file is located, likely in Downloads.
4. Right click on that entry and choose open with GDebi and proceed to install it.
5. Once installed, if you go to Menu and type in key mapper you will see the icon.
TERMINAL WAY (CLI - Command Line Interface)
1. Having launched Terminal, type in and enter the following, it presumes you have downloaded the file into Downloads, if not replace the path
Code:
cd Downloads
sudo dpkg -i key-mapper-0.6.0.deb
exit
If successful, the Key Mapper will be in your Menu.
SUGGESTION ENDS HERE
However, I do not like to recommend to users a solution I have not tried myself, and when I was following the above steps and then tried launching Key Mapper I received an error (sorry, did not record it at the time).
So I will keep looking but my friends above may have some better suggestions.
Cheers
