Quickly change the indent type (tabs or spaces) & size for the current editor from the Atom command panel.
Install the package with
apm install set-indent
There are no default keybindings but you can add your own by editing your
keymap.cson file, eg:
'atom-workspace':'ctrl-alt-1': 'set-indent:tabs-4''ctrl-alt-2': 'set-indent:spaces-2'
