[Solved] Regular expression in search

[emf]

I would like to change all
##,
to
*##,

where # is a digit, an * just a symbol (it could be something else).
Can I do this in 1 search and replace all using regular expressions?

AltSearch from the extensions repository should do this for you.

Why did you post this in the 'Macros' branch?

In a RegEx a single digit is represented by "[0-9]", two subsequent digits by "[0-9]{2}" To make the finding available in the ReplaceWith you can use the RegEx "([0-9]{2})" and reference the found string by "$1". I use 'Prefix' now for what you represented by an asterisk.
Search for : ([0-9]{2})
Replace with: Prefix$1
With Prefix = § applied with 'Replace All' to foo1978bar this would result in foo§19§78bar.
If this is not what you want, please explain your intentions more precisely.
