Typical FS navigation is one of two things: the 'z' script (https://github.com/rupa/z) to jump directly to any commonly-used directory, or FZF to get the directory tree under the PWD. Both of these are functions in my bashrc, with keybindings, and they insert the selection into the input. So alt+o selects from the 'z' database and I can write things like `mv *.jpg <alt+o> memes<ret><ret>` I do a lot of things like `vi <ctrl+t>benis.c$` in source directories. Also, a flygrep command that works basically the same way.

I also have some commands that list files into dmenu, for opening media, games, etc. Those are bound through sxhkd.
