## Incrementing And Decrementing Numbers

21. 3. 2020; Vim

Some of you might know that pressing / in command mode increases/decreases the next number on the line the cursor is currently on:

There is 12 apples. --> There is 13 apples.


But did you also know that it can handle other bases and even alphabetical characters (worked for me but might need to be configured – see this wiki article):

There is 0b1100 apples. --> There is 0b1101 apples.
There is 0xc apples. --> There is 0xb apples.
This is 'a'. --> This is 'b'.


Equipped with this knowledge, one can easily add to and subtract from any number (10), create a list of numbers in a given base (a relatively simple macro), play around with caesar cypers and generally do many things that would likely not be possible in other text editors.
