# revelation.lua
Provides Mac OSX like 'Expose' view of all clients.
Provides Mac OSX like 'Expose' view of all clients.
It is modified from the original revelation.lua.
##Changes from the original revelation
* add support of multiple screens. Now the revelation will be trigged on
the on the multiple screens at the same time.
* The way of select and active the client was changed. The previous
movement by the keystroke "j,h,k,l" was deprecated and is replaced
by the same way in the module hint.
