Use the character map (charmap.exe) from Windows to find symbols and special characters.
The keystroke is Alt+0169 on the number keypad.
Yes I now recall this has to be done on the numeric keyboard section. Thank you
Sometimes my computer does not use the same fonts as the ones on the keys. For instance “?” shows up as “E” with a apostrophe. When I key in the alt 069 I get an E. How can I fix this?
It's not 069 it is 0169.
I will have to make a note of that somewhere
Just to expand on the correct answers above-
ON A WINDOWS 10-PC: [CTRL+ALT+C] will (may?) work in a Word Document- but NOT in Lightroom!
or- HOLD DOWN [ ALT ] AND TYPE 0169 ON A ‘NUMERIC’ KEYPAD.!
(Note: 0169 on the top row of keyboard does not work!! Laptops will work with [Fn] and embedded numeric keys. [ALT + Fn + embedded 0169)
ON A MAC: TYPE [Option/Alt + G ] ( http://www.wikihow.com/Make-Symbols-on-a-Mac )
.. and, as already mentioned ... on a Windows PC start charmap and you will find all characters and symbols available including the option to copy them and the keycode that can be used.
I never knew this program existed.
I have already solved the issue by using the numerical keyboard to input the numbers.
