Once I transfer my raw files to a destination folder, my first step in post is to change the file name to something meaningful (to me). Often, I wish I could press F2 and rename a photo as I work through the folder in the Develop module. However, F2 rename only seems to function in the Library module.
Sure would be nice to have F2 - Rename available in other modules, especially Develop.
Sorry about the delay in our response. As you've mentioned that F2 shortcut is only limited to rename images in Library module, I'd suggest that you post a new discussion on our Lightroom community so that our Engineers ca look into your request and work on it accordingly.
