Alternative keys or app for navigation keypad (call, menu, escape, end keys) above d keyboard ?

Please what are the alternative keys for the blackberry keys ( call key, menu key, escape key and end key)? Those keys of mine are non functional now and since I am in another country can't do replacement ( warranty still valid) till weeks after I return to my country. So what other keys or combination of keys can be used to accept a call ( when the call key is not functional), or alternative keys or combinations when the menu key is non functional , how to go back or return when escape is non fictional and how to end a call when the red end call button is non functional? Or is there an app out there ? Since the touchscreen and trackball works fine

I am not aware of any apps that can serve to overcome your broken or mis-functioning keys.

You have pulled the battery and/or restarted the phone?

Not necessarily looking for an app, if there are alternative keys or combination of keys on the keyboard that would be better. Btw there is an app for broken trackpad.
And of course I have long done the battery pull out before opening this thread

Any?..........
