# The different keys depending on the terminal
# You can change the folowing bindings
#
# WARNING FOR UNIX USERS ONLY : 
#           if you are running on a unix computer the only 
#           special key names you can use are 'esc' and 'tab'
#           Thus if for instance you want to assign 'f1' to 
#           the action of performing file completion, you must
#           first find out what the key sequences is associated to 'f1'
#           by your terminal (for that purpose just type 'f1' in the terminal window
#           and it will give you the associated
#           key sequence) and then do _filec='the_key_sequence'.
#
#           Let us note that this is true only for terminal bindings.
#           If you want to assign 'f1' with a binding in a lastwave graphic window
#           which is not the terminal you must use the symbolic name 'f1'
#
