The WASD keys get now lighted accordingly.
This allows to switch quickly between lighting profiles using the command line, a script or even [[https://direnv.net/][direnv]].
This allows to switch quickly between lighting profiles using the command line or a script.
Profile switching per current work-directory can e.g. easily be achieved with [[https://direnv.net/][direnv]].
An instruction how to apply profiles automatically while running *Steam* games can be found below.

Not set lights are turned off.
** Steam
*Steam* allows to set various launch options for games.
This functionality can also be used to apply lighting profiles before the startup and after the exit of a game.
Lets assume you created a profile called =my_favourite_game= and one called =default=.
Right click on your favourite game in the Steam launcher and click /Properties.../.
On the bottom of the /General/ section is a text field, labeled /launch options/.
Insert the following command:
#+begin_src sh
rzr my_favourite_game & %command% && rzr || rzr
#+end_src
The first command applies the profile =my_favourite_game= as usual.
=&= ensures that the next command is called even if the first on failed.
Your game should start even if *rzr* failed or you have messed up your profile file.
Steam then substitutes the =%command%= part with the binary of the game and runs it.
The =&&= waits until the first command exited correctly, speaking you quit the game.
If this is the case, the command =rzr= applies your =default= profile.
In the case of a game crash, the =|| rzr= part makes sure your =default= profile gets applied anyway.
It is neccessary that *rzr* is installed correctly and available in your =$PATH=, otherwise Steam will not be able to call it.
** Troubleshooting
Make sure your user is in the =plugdev= group to access the OpenRazer daemon.
