Description of Problem:
The new rxvt-2.7.8 greek keyboard support defaults to using Mode_switch for changing between western and greek fonts

Version-Release number of selected component (if applicable):


How Reproducible:


Steps to Reproduce:
1. launch rxvt
2. press Mode_switch (altgr)

Actual Results:
Touching altgr (Mode switch leaves greek character set on).


Expected Results:
In many European countries (Finland, Sweden, Norway... I'm not sure what others... Germany, France?) altgr (Mode_switch) is used to compose characters like $, #, @, \, ~, |. It work like shift - you press it with for example '+' (altgr-+ -> \). 

Additional Information:
You can work around this with echo "Rxvt*greektoggle_key: Hyper_L" >> ~/.Xdefaults. 

But this is hellova announing default - altgr is the second most used modifier in Nordic countries. I don't think you want to leave this on by default. See README.greek in rxvt package, it can be disabled. Or at least change the default key to something else than 
altgr.
