 Replying to [comment:99 mtd]:
 > FTR, this recurred for me a week ago, and I "fixed" it again yesterday
 by waving the same dead^W^W^W repeating the disassembly process.

 I'm (getting) annoying here, but it's happened again, starting four days
 ago.  It usually takes that long for it to be bad enough that I want to
 throw the keyboard out the window...I disassembled it instead, and now
 it's working fine (Alt/Ctrl unstuck) again.

 Two new observations:

 1) I had to fiddle around with the keyboard cover/surface (what has the
 letters printed on it) and the actual contact layers below, this time,
 before it started working.  I had the top cover/surfacce peeled off,
 starting at the left, to about the Y key, but even pressing on the 'real'
 keyboard itself, it seemed as if the keys were stuck.  I don't know how I
 got it unstuck but pressing down with multiple fingers bunched together on
 the 'real' keyboard and then applying pressure as if to push the membrane
 around (various directions) finally seemed to do it; and
 2) To try and mitigate the issue before I had to resort to disassembly, I
 had pulled the top membrane progressively further out from under the left
 side/bumper...this appeared at first to help but at the end I had the left
 side of the keyboard membrane out entirely and was still getting the stuck
 keys.

 Anyway I think I will stop spamming this ticket with this type of issue,
 unless things change, as since it appears from my updates that I went 4
 and 2 weeks between disassemblies (which isn't a compelling trend :)), I
 expect that to continue to be necessary until I can find out what is
 causing the behavior to recur.
