This probably been addressed in the wiki but I didn't understand how to fix...

When running xcadabra (or xmaxima) I need to use curly brackets to make
tensors (i.e. A_{a,b}). Fortunately, in LDXE it works fine because I have xbindkeys
set up to make these. For example, "control left arrow" is defined to make a {.
However, when using debbie In xterminal the new key defintions
did not work. I tried "debbie xbindkeys" and "debbie-sue xbindkeys" to see if the keys
would be redefined but no luck.

Any idea how to fix this?
