How do I decrement a number under the cursor?
Answer
<C-x>
Explanation
The <C-x> command decrements the number under or after the cursor by 1. It is the counterpart to <C-a> for incrementing.
How it works
<C-x>finds the nearest number and subtracts 1- Works with decimal, hex, octal, and binary numbers
- Accepts a count:
5<C-x>subtracts 5
Example
retries = 3
Pressing <C-x> changes it to:
retries = 2
Tips
<C-a>is the increment counterpart100<C-x>subtracts 100- Numbers can go negative
- Useful for adjusting array indices, port numbers, and counters
