[Maurizio Marini]

When I use telnet inside Konsole,
to close telnet:
Escape character is '^]'

once upon a time, pressing 
Contr and ] 
closed telnet session, now it enlarge fonts, sadly.
I have searched into 

Konsole/Settings/Edit currente Profile.../Keyboard
Kde Menu/Settings/System settings/Shortcuts and Gestures

but I haven't found anything relevant
please help, to close a telnet session I have to open a 2^ console and kill -9
telnet pid
