It is the year 87,539,319 and solitary space-walking is now commonplace, many people travel into space by themselves, propelled by nothing but a jetpack on their backs, programming their course with a personal computer and keyboard as they go.
You are one such person; you were out on a lovely, peaceful spacewalk, when, all of a sudden, you were ensnared by the gravity of a black hole!
As you plummet towards this black hole, spiraling ever faster inwards, you realise your one chance of survival is to broadcast a distress message, and hope a nearby ship comes to rescue you.
So, you break out your keyboard, and begin typing away a program.
Your program can be in any language, and must print
HELP! to stdout (your PC broadcasts all stdout far into the depths of space.)
However, as you are near a blackhole, your keyboard is slowly being ripped to shreds!
Assume you are using a QWERTY keyboard like the one below, and that the blackhole is to your left;
after every keypress, the left-most row of your keyboard (keys covered by left-most red line) is ripped off and flung into the black hole!
So, your first keypress could be any key on the keyboard, but from then onwards none of the leftmost Tab, Caps, Shift, Ctrl or ` keys may be used, at all. (r-shift and r-ctrl can still be used)
After the next keypress, the keys 1, Q, A,Z and Alt are flung into the abyss, and may not be used thereafter. After that, you lose Space, X, S, W, 2 and so forth.
Obviously, you want to complete your program as quickly as possible, so that rescue-time is increased; therefore, this is code-golf, and the shortest program in key presses wins!
Each answer should provide a list of keypresses, so, if my answer was this program (in the language squardibblyack)
a keylist could look like:
Shift!HELP release shift \.
I'm worried this challenge might be too difficult, but I'd love to see the kinds of answers submitted!
