At the moment, there is no option in preferences to change the shortcut for Rename to something other than F2.
My laptop has other functions assigned to the F keys such as volume, brightness etc. It is possible to toggle it back to standard F keys but I don’t want to.
Currently the only way to rename a layer is to select the 3 dots and then press F2 or manually select Rename. I guess it should be another request but I think there should be more access than that for renaming layers such as in the layer properties at the very least.
