-- modMask lets you specify which modkey you want to use. The default is
-- mod1Mask ("left alt").  You may also consider using mod3Mask ("right
-- alt"), which does not conflict with emacs keybindings. The "windows
-- key" is usually mod4Mask.
--

--
-- Default offset of drawable screen boundaries from each physical screen.
-- Anything non-zero here will leave a gap of that many pixels on the
-- given edge, on the that screen. A useful gap at top of screen for a
-- menu bar (e.g. 15)

-- Fields are: top, bottom, left, right.

--
-- numlock handling:
--
-- The mask for the numlock key. You may need to change this on some systems.
--
-- You can find the numlock modifier by running "xmodmap" and looking for a
-- modifier with Num_Lock bound to it:
--
-- $ xmodmap | grep Num
-- mod2        Num_Lock (0x4d)
