IceWM comes with default shortcuts (like the ubiquitous Alt+Tab) as we have seen there are a ton of them in the Preferences file.

For example:

Ctrl + Alt + t will give you the xterm or whatever terminal you want.
Ctrl + Alt + will put you in the workspace you specified

Playing with it, i found out that the "Windows" key in my keyboard will take the place of the 'ctrl+alt' combo. Thus, i save one key:

Windows key + t = xterm
Windows key + 4 = will take me to the workspace 4

Now, not knowing didly about macros/scripts/programs, i still thought that one key, was the best way to launch my apps, if it worked with 2 keys, why not with one key? This is what i changed in my ~/.icewm/keys and ended up with:
