I don't think I've EVER used Scroll Lock.

I've heard it's still used in Excel sometimes but otherwise, is there much use for it anymore?

 

EDIT: Just had a look [ame=http://en.wikipedia.org/wiki/Scroll_lock]here[/ame] and found very few uses for it.

How random! 'I've never used scroll lock before but I'm going to create a post asking if its days are numbered' :D:p

 

For what it's worth, I've never used it either! :doh:

LOL... I was thinking how random it was myself.

 

I accidentally hit it instead of Print Screen and thought, "I've never used that key for ANY purpose. What a waste of key and LED.......... I should post this on various online forums" :D

Or there is the SysRq key - never used that either

I like this: [ame=http://en.wikipedia.org/wiki/System_request]System request - Wikipedia, the free encyclopedia[/ame]

 

Especially where it says:

"System request (often abbreviated SysRq or Sys Req) is a key on keyboards for PCs that has no standard use"

 

??:confused:

It's called backtick, commonly used as a field specifier in sql and escape sequence in many shell systems.

 

Sql example:

SELECT `id`, `name` FROM user WHERE `name`='Fred';

 

Bash example:

for a in `ln *.txt`; do cat $a; done

Pause|Break is just as useless these days, isn't it?

 

Use Pause to halt the computer on the BIOS/CMOS screen. Ideal for catching debug info before it moves onto loading the OS.

 

Then again, a keyboard without those three at the top would just look wrong.

 

They sure do!

Win + Break displays the local system properties in Windows. In most Bash variants Ctrl+Break is the same as Ctrl+C, raising a SIGINT signal. Edited by powdarrmonkey
siging is not a valid unix signal (except for very large values of g)

Speaking of useless keys, what's the key above tab and below escape on the left hand side for?

 

In PL/1 (the rival to COBOL back in my days as a mainframe programmer)

 

¬ was used as NOT when coding

 

e.g.

IF VARIABLE ¬= VALUE

THEN ...

 

| was used as a logical OR

 

and

 

|| was concatentate

Or pausing the PXE screen when network booting, so you can read the GUID in comfort when prestaging an image.

Not if you're trying to read something from a POST.
