I mostly SSH to Linux, but when I use a Linux Desktop, I struggle to get the key bindings to my taste.
Here's an example on a Sun keyboard, labelled with a diamond: http://xahlee.info/kbd/iold51593/Sun_Microsystems_Type_6_Key...
Oh, absolutely.
A small mercy is that software on Linux never seems to use the Windows aka super key in shortcuts. So i set up my desktop environment such that all its shortcuts use super. It means i have a completely nonstandard setup, but at least it means there are no collisions!
Apps mostly steer clear of ctrl + alt + funky key combinations (ie not letters), so you can have those for locking, rebooting, etc.
But it would be lovely if this was systematic, codified, and standardised.
It did. It's still available in Windows 10.
And it's what everyone used throughout the eighties and most of the nineties, until Microsoft copied the silly Cmd-X/C/V (only with Ctrl in stead of Cmd) from Apple for Windows 95 or thereabouts.
I wish this had caught on. CTRL-X/C/V is okay-ish until you get to different platforms and/or need to use the terminal.
I also wish we'd have stuck to a clearer separation of which modifier keys apply to the OS/desktop level, which ones are app level, and which ones are text/input level.
