Is there any way to change it to an upper case one rather than going through all the rigmarole of locating the cursor ahead of the mistyped letter, backspacing, holding down shift and retyping the letter?
in microsoft word if you highlight and right click and go to font you can change it there. although i wouldnt think this would be any quicker. It is useful if you want to chage a lot of letters at once.
In Word, if you highlight the word or words, and hit Shift+F3 it cycles through all lowercase, first letter capitalized and all uppercase.
