#### 4.5.5 ReplaceAll

Syntax: `ReplaceAll [`string`]`
Abbreviation: `RA`

is similar to `ReplaceOnce`, but replaces all occurrences of the last search pattern with the given replacement string.

If the optional argument string is not specified, you can enter it on the input line, the default being the last string used.

Note that `Undo` will restore all the occurrences of the search pattern replaced by `ReplaceAll`. See Undo.
