## 18.10. Typing in Uppercase Without CAPS LOCK

You may want to input text in all uppercase letters. Using CAPS LOCK in vi can be a pain because you have to release CAPS LOCK almost every time you want to type a vi command. Here's a nice way to type lowercase letters during input and ex modes; they'll be mapped to uppercase automatically.

Try putting this in your .exrc (Section 17.5) file:

>     map! a A
>     map! b B
>     map! c C
>       ...
>     map! z Z

Anytime you type (during text-input mode) an `a`, the editor will map it into `A`. What's that you say . . . you don't want this all the time? Just put it in a file called .f (for FORTRAN), and type:

>     :source .f

when you want FORTRAN mode. Of course, you can define a function key (Section 18.2) to `:source` this.

[After that, anywhere you want a lowercase letter, type CTRL-v first to cancel the map temporarily. For example, to type the command `:w`, type : CTRL-v w.

You can also go into the ex command mode by typing the vi command `Q`. That takes you to the ex colon (:) prompt -- where the map! macros won't affect what you type. To return to vi mode from ex command mode, type `:vi`. -- JP]
