Press Shift Key to turn off Caps Lock

Actually, I get asked this quite a lot

There is, however, a very good reason to prefer this (old) „Typewriter Caps lock“-behavior over the new default, and it's simply this: if „Press the SHIFT key“ (instead of „Press the CAPS LOCK key“) is selected, then the behavior of „Caps lock“ changes from being a „toggle key“ to being a key that can only be used to turn „Caps lock“ on – to turn „Caps lock“ off, one has to press (either) one of the Shift keys.

This can be advantageous for touch typists, who are used to writing long passages of text without looking at the keyboard, and especially so if they're (C/C++) programmers, who may still regularly find themselves typing in variable names of CONSTANTS_IN_UPPERCASE.

That's because, if Caps lock is not a toggle key, it's not necessary to keep track of its current „toggle state“ in your head:

• If I want „Caps lock“ to be on, I can press CAPS as often as I like. If it happened to be enabled already, nothing changes; otherwise, I can be sure it's enabled afterwards.
  
  
• If I want „Caps lock“ to be off, I can simply press SHIFT

This sounds like a hypothetical advantage, but it's not. I work as a programmer, and I often find myself typing in code like the following:

/* Some debugging code; will only be included in debug builds: */
#if defined _DEBUG

Afterwards, I may pause a little, to think about the code line I would like to type in next. Now, if „Caps lock“ is a toggle key, I may (once I decide to continue) be unsure if I actually remembered to turn „Caps lock“ off at the end of ‘_DEBUG’.

Did I? Did I not? – The only way to be sure, is to look.

This is not so, if the „Press the SHIFT key“ behavior is enabled. If unsure, I can just press SHIFT once, be sure of the set state, and merrily continue may way.

That, for me, is the single most important reason to prefer the „Press the SHIFT key“ setting. Also, interestingly, this used to be the default behavior in the old days … at least, until Microsoft decided to ditch Windows 9x in favor of Windows NT¹.

¹ Actually, my memory could be wrong in this regard and I'm not completely sure … maybe someone more knowledgeable in those matters can confirm that the „Caps lock“ default behavior was indeed changed during the switch from Windows 9x to Windows XP?

 

Left Shift, Caps Lock and Tab keys not working

Since update KB3149135 installed on my desktop the left shift, caps lock and tab keys no longer work.

Help would be appreciated.

 

my left shift, tab, and caps lock keys no longer work after an update on 3/25/2018

to my knowledge nothing has ever been spilled on the keyboard, and the problem keys mentioned were all working before today.

i may pop the keys off later and see if anything has gotten caught underneath.

Edit: I have just popped off the keys and there wasn't much but a bit of dust. I cleaned it up and the keys seem to be working now, but my caps lock dosn't turn off unless I press any shift key.

(I do not need to hold shift to turn off the caps lock, but caps won't turn off by pressing the caps key.)

Thank you for the suggestion.

I wouldn't have suspected a little dust since most of my issues seemed to have started today.

edit; now shift caps and tab are not working again i don't know what happened they were working fine for a few hours. maybe there is some strange hotkey or something that i am pressing.
