[openbox] Launching applications

[Manolo Martínez]

Hello everyone,

I have a number of keybindings for launching common applications. Currently,
say, A-F5 launches mutt in a urxvt terminal and, if I press that key
combination twice, I get two mutt instances.

Is there any way to find out whether there is already a window running mutt
somewhere and, if so, instruct A-F5 to raise and focus that window, instead of
launching a new one?

Cheers,
Manolo
