" `gh` - toggle hidden files
" `%` - Create a new file
" `d` - Create a new directory
" `R` - Rename file
" `D` - Delete file/folder
" Then the gauntlet for copy/move:
"   `mt` - Mark the target directory
"   `mf` - Mark a file or directory
"   `mc` - Copy all the marked files/directories to the target directory
"   `mm` - Move all the marked files/directories to the target directory
