My work is audio transcription. My normal production involves making copies of template files, and then renaming them to match the name of an audio file I'm transcribing. The normal procedure is to right-click on the audio file in Caja, click on Rename, and then copy the name to the clipboard. The way this always used to work before yesterday afternoon is that the filename, not including the extension, is highlighted. I copy that, then apply the rename procedure to the .doc and .xls files, pasteing in the name of the audio file.
Yesterday afternoon something changed. When I right-click on a file in Caja, and click on Rename, the entire filename plus extension is highlighted. There appears to be no way to un-highlight the extension. This makes it impossible to use copy and paste to rename a file. Oddly, the behavior is different on the desktop. There I can rename the way I used to be able to in Caja.
So, I have a work around, but it's annoying.
I thought about using rename, and copying the file name to a text file, editing it there and renaming the other two files as appropriate. When I pasted the filename, I got the entire pathname, starting with /home.
During this time I've logged out and back in, and ran some upgrades that required a restart. Neither logging out nor restarting changed the behavior of Caja.
This morning Caja rename is back to normal.
Any ideas on what happened and how to fix it if it happens again?
