How do I toggle the case of all characters in a visual selection?

Question

Accepted Answer

`~ (in visual mode)` In visual mode, pressing `~` toggles the case of every character in the selection. Lowercase becomes uppercase and vice versa.

## How it works

- Select text with any visual mode
- Press `~` to toggle case
- Each character flips individually

## Example

```text
Hello World
```

Select with `V`, press `~`:
```text
hELLO wORLD
```

## Tips

- `U` converts selection to uppercase
- `u` converts selection to lowercase
- `~` toggles each character individually
- `g~{motion}` toggles without visual mode
- Works with all visual mode types including block
