Solved Make F4 -or any keystroke combo open/close Calculator

November 22, 2020 at 15:02:05
Specs: Mojave, 64 GB

I tried using Automator to program F4 to launch Calculator.

F4 works to launch Calculator in:
Microsoft Word for Mac 2016
Microsoft Excel for Mac 2016

But it works erratically.

In some of the above apps tapping F4 as soon as I opened the app did not work 
the first time to launch Calculator. 
I had to first mouse click my "Launch Calculator F4" service, Calculator would launch, 
then I'd quit it, and then F4 worked to launch Calculator with just a tap on F4. 

However . . . F4 does NOT work to launch Calculator in these apps:
I get a "bonk" sound when I press F4.
My created "Launch Calculator F4" is under Services and when I mouseclick 
it Calculator launches.

F4 also does NOT work to launch calculator in FIREFOX (v83.0)(64-bit):
. . . But this is different: 
When I press F4 the FireFox name in the FF menu bar flashes white letters 
on a blue rectangular background and does NOT launch Calculator.
However, my created "Launch Calculator F4" is listed under Services and when 
I mouse click it Calculator launches.

I use FireFox as my browser.

I would like to know how make F4 --or another function key or keystroke combination--
 work in Firefox  --as well as--  in ALL Mac apps to open and close Calculator.

Please advise!

There's an option in Mac OSX systems to re-allocate "all" of the F keys to do what ever you want them to do. I've re-assigned F1 to print screen - using the steps given in this (to me very helpful) article:

To run calculator I'm guessing you would select "app shortcuts" in the left hand column of the "keyboard" window and then locate the calculator app itself?

Exactly JohnDohe, I have been using their site for Windows, Linux & all my programs for over 20yrs. You get a huge amount of info, also each program has a star rating, top one is from users & the bottom one one is from the staff member who reviews the program. Click on the top star ( yellow ) to add your approval. They also make you aware of the security side of things. If nothing is said, it is a clean secure program.

Thanks for the feedback.

Yes I agree it doesn't work as I thought it might; based on my Print Screen F1 key setup. (I set F1 to print screen.)

But it can be made to work using "command F2" (I tested it using F2 so obviously it could be any F key once they're released from the default setting.) Presumably one could use the option or control keys in the same double or triple combination.

Which having said, dun... I found this; which seems to say that one cannot assign a key to run app; only can apply to built-in menu commands etc.?
