See if Ctrl-[ works. I tend to hit that instead of Esc everywhere I'm using a vi-like after having a weird keyboard issue that nerfed my Esc key for a while (long and uninteresting story) and then finding that Ctrl-[ was more comfortable for me anyway. (of course that may not work at all in the lambda editor, I'm mostly using it in terminals with heirloom-ex-vi, but seems easy enough to TIAS some time)
