CTRL-H in emacs running on my xterm, then this is interpreted as backspace and the character before the point is deleted. I've found various discussions about the "opposite" issue (pressing backspace invokes help), but was unable to modify them to my needs.
How can I access help commands (like the describe functions) from a
emacs -nw running in an xterm with the keystroke
