in F2 renaming, possible to remove and insert characters NOT based on regex capture groups?

[dwilbank]

In the results list, after selecting a few rows and hitting F2, I was hoping to be able to delete, say, the last 10 or so characters from multiple files, even if they are all dissimilar.

Right now, I can only manipulate around the "capture" groups that regex has found, and if the last 10 digits of every file is not identical, those digits are not displayed for me to manipulate.

Is there a non-regex renaming mode?

P. S. Directory Opus's alt-R renaming is the type of "edit anywhere by position" mechanism I'm talking about

Thanks!

Only possible to remove 10 characters with regex.

For example:
Check Regular expressions.
Check ignore extension.
Old format:

^(.*)..........$

New format:

\1

Non regex mode only supports wildcard %1-%9

Thanks!
My version seems to be missing the ignore-extension checkbox though...
