Question regarding use of regular expressions in find/replace [message #270649]

I don't know if this is the correct newsgroup for this question, but I
am having trouble using the reg ex support in the File find & replace.
I entered a find pattern of:

Draw[a-zA-Z0-9]+[(]

and I basically want to change all such occurrences to begin with a
lowercase d. I tried the following as the replace string and nothing
really happened in the file:

\l$

I admit I'm pretty new to regular expressions, but this seems to be the
correct approach based on what I've read. The ctrl+space help doesn't
really help.

Thanks,
David

My Ctrl+Space help tells me to use
- (U) to mark U as capturing group
- \i in the Find field to refer to the capturing group number i
- $i in the Replace With field to refer to the capturing group number i

In your scenario you would use (...) to declare a group in the Find
field and $1 in the Replace With field to refer to the first group.
