-.TH RIOW 1
-.SH NAME
-riow \- keyboard-controller for rio(1)
-.SH SYNOPSIS
-.B riow
-[
-.I -s label
-]
-.SH DESCRIPTION
-.I riow
-provides keyboard controlling for
-.I rio(1)
-in the manner of
-.IR i3 ,
-.I sway
-and so on. It does so by working with
-.I /dev/kbdtap
-(see \fIrio\fR(4)) and
-.IR /dev/wsys .
-.SS Running
-.I riow
-filters all key combinations that include
-.B Kmod4
-modifier, so it has to be placed
-.I last
-in the chain of programs using
-.IR /dev/kbdtap :
-.EX
- </dev/kbdtap ktrans | \\
- reform/shortcuts | \\
- riow >/dev/kbdtap |[3] bar
-.EE
-Note that the current desktop number is printed to fd
-.IR 3 .
-.SS Keyboard shortcuts
-.TP
-.B Kmod4+0…9
-Switches to the specified virtual desktops. There are ten in total.
-.TP
-.B Kmod4+Shift+0…9
-Moves the current window to the specified virtual desktop.
-.TP
-.B Kmod4+f
-Toggle between fullscreen and normal mode for the current window.
-.TP
-.B Kmod4+s
-Toggle "sticky" mode for the current window. In this mode the window is staying
-while the user is switching between desktops. By default, programs like
-.IR winwatch ,
-.IR catclock ,
-.IR kbmap ,
-etc are in sticky mode. Additional programs can be added to that list on startup by
-specifying their labels with
-.I -s
-option.
-.TP
-.B Kmod4+enter
-Spawn a new
-.IR window(1) .
-.TP
-.B Kmod4+h/j/k/l
-Focus left/down/up/right.
-.TP
-.B Kmod4+arrows
-Move the current window in the specified direction.
-.TP
-.B Kmod4+control+arrows
-Same, but in bigger steps.
-.TP
-.B Kmod4+shift+arrows
-Resize the current window.
-.TP
-.B Kmod4+shift+control+arrows
-Same, but in bigger steps.
-.SH SOURCE
-https://git.sr.ht/~ft/riow
-.SH BUGS
-Yes.
