Any better title is welcome. All of a sudden when I press:
- d - I either see d typed in or I get a print screen window
- e - I either see e typed or I see volume bar rise
- c - I either see c typed or I have many different effects (depends on context)
So far I'm unable to tell what is the "trigger" or "toggle" for this peculiarity.
I'm frankly at a loss what to investigate. Few findings:
- while this first manifested in a browser (FF + Vimperator) this is NOT browser limited
- GVim, terminal even tty (I switched to it) can have that
- In tty d becomes
\; and c becomes
^[[5~b and presses Enter.
kern.log I see no entries when tailing when I press d even when I see volume bar increasing upon keypress
- I see no strange shortcuts when I open
Keyboard Shortcuts window
Any clues? I had not run any updates recently, nor have I installed something. This interrupts my work to the point I had to borrow someone else's laptop to type this.
- 3 - deletes first character in line and puts cursor there
- # - inserts last cut or highlighted (I'm unsure here) thing
These have been tested only in terminal and tty and login shell.
Another keyboard - currently none at hand that I can plug in.
@Mordoc FN key inputs:
I don't think it's jammed key. Fn key works as expected except for volume. Pressing Fn+e doesn't give me e, though I had few times earlier, before posting this question where I had "toggled" this with function key. This however is not consistent.
Normal volume keys were on F2 and F3 and they do not work now. Mute key works as usual. So, it rather isn't the case for jammed key but it still found us something new.
Problem "solved" itself equally suddenly as it had manifested.** Leaving this open for a week or so. Vasa1 - your comments were closest to the cause I think, so feel free to post them as an answer, along with "another keyboard" suggestion.
