How to restart icewm from the command line?

view full story

http://unix.stackexchange.com – I'm looking for a way to bind for example the Ctrl+Alt+Ins key combination to a command line that would restart icewm (just to make it read the configuration files again and be aware of the edits). So what should go into that .icewm/keys file ? key "Alt+Ctrl+k" <tab> <...> ? (HowTos)
