What about typing a real omega?

Here you have one so you can copy it Ω

kcharselect can be of help if you don't know how to type weird symbols with 
your keyboard

Nope, that's not possible either, this is something we alaways wanted to do, 
for example, double clicking on the icon to select and keep the tool selected 
after use, but never got into it.
