I have some numbers in a file. How do I increment or decrement the

numbers in the file? You can use the CTRL-A key to increment the number and the CTRL-X key to decrement the number. You can also specify the number to increment/decrement from the number by specifying a count to the key. This works for decimal, octal and hexadecimal numbers. You can change the base used by Vim for this operation by modifying the ‘nrformats’ option.
