`rofi` is an X11 popup window switcher. A list is displayed center-screen showing open window titles, WM_CLASS, and desktop number.
`rofi` is an X11 popup window switcher. A list is displayed center-screen showing open window titles, WM_CLASS, and desktop number.

`-show` *mode*
Open rofi in a certain mode.
For example to show the run-dialog:
rofi -show run
This function deprecates -rnow,-snow and -now
`-switchers` *mode1,mode1*
Give a comma separated list of modes to enable, in what order.
For example to only show the run and ssh dialog (in that order):
rofi -switchers "run,ssh" -show run
Custom modes can be added using the internal 'script' mode. Each mode has two parameters:
<name>:<script>
So to have a mode 'Workspaces' using the `i3_switch_workspace.sh` script type:
rofi -switchers "window,run,ssh,Workspaces:i3_switch_workspaces.sh" -show Workspaces
Switch between modi
