[ulipad:4020] Spell check

[Werner F. Bruhin]

I am just trying out the spell check functionality and have a couple of 
questions.

1. Is it possible to add some short-cut key to invoke spell check?
2. How can one add terms not found in the dictionary to a custom/user 
dictionary.  This will make it must easier to spell check .rst files.

Appreciate any tips on this
