Here is my first attempt to write this question while I had the issue. Because of the issue, I was unable to click on the post question button:
I just woke my computer from sleep and my keyboard is not behaving.
For example, the modifier keys are reversed so pressing arrow left
highlights text rather than moving the cursor. I also have my Caps Lock
key reversed, and I get a<when I try to type a comma and a>when I
type a fullstop, yet holding or not holding Shift does not correct this.I have tried unplugging the keyboard and plugging it back in using a
different USB port with no improvement.In the past, the only solution I've found is to reboot the system. Else
I'm stuck holding Ctrl to click on links so they don't open in new
windows, etc.
After restarting my computer I'm tempted to put the punctuation in above. Basically, all the modifier keys Ctrl, Alt, Shift, Caps Lock had been reversed so that the lights and the key combinations did not work as expected, and using my computer became far more difficult. For example, I could click on some text, and click elsewhere, and it would select everything inbetween as if I had held the Shift key.
This has happened several times and always when I've woke my computer from sleep.
Note: It's not sticky keys, it was one of the first things I checked for

The feature that provides the functionality of what you are experiencing is called StickyKeys. It's not new to Windows 7, and it has been in since at least Windows XP that I know of, possibly earlier.
To disable in Windows 7: Menu Start -> Control Panel -> Ease of Access -> Change how your keyboard works (or make the keyboard easier to use) ->
All your settings are in here. I personally untick everything when I build a new PC. Make sure nothing is ticked and also go into setup StickyKeys and untick anything in here.
I cannot explain why coming out of sleep is causing this, but hopefully this should stop it from happening.
