This is probably the weirdest software problem I have ever come across.

When I press L key in cygwin command line I see no reaction whatsoever. All other buttons on the keyboard work perfectly. In ALL other programs (including vi and cmd.exe, as shown on the screencast) L works.

Does anyone have ideas what could cause this? Reboot, cygwin reinstallations did not help. Reproducible in both cygwin 32 and 64 bit.

I have Windows 8 64bit.

Captured a small video describing the problem (sorry, youtube messed up the quality and the sound, as usual): http://www.youtube.com/watch?v=yjJ9FEwWVBs

    I suggest asking on the cygwin mailing list cygwin.com/lists.html (email a blank message to [email protected] ) that should then subscribe you and say how to email the mailing list (probably will be [email protected] or something) can unsubscribe when done. [email protected] in case it's high volume.

    out of interest is it mintty.exe or is it from the command prompt running cygwin.bat and is there a difference in whether 'l' is recognised? and can you paste an 'l' in from charmap? just things that may be worth looking into.

    re '2' I guess you mean to cygwin command line cos cmd command line is fine

The problem turned out to be related to corrupted ~/.inputrc file

bind '"l":self-insert'

this is what solved the issue for me. Also look at this answer for more details.
