Question about selecting multiple files

Things I have tried

What I’m trying to do

To select multiple files on a PC in the file manager, there is a combination of alt + mouse. This is a very unusual combination. In addition, I use Linux and there are some conflicts with the work of keyboard shortcuts with alt. I’m much more used to using ctrl+mouse to select multiple files. Can this be configured somehow?
I haven’t found any way to select multiple files on Android. Or is there no such functionality on Android? This is very sad.
