I know, that this bug is not critical, but I want to give you a feedback.
If you want to rename a file, you press shift-F6. Then you are able to jump between the words via Ctrl-Left / Ctrl-Right. The Cursor stop at the beginning of each word and TC detects special characters like "-" (minus).
When you want to copy / move a file via F5 or F6, the pop-up dialog also allows to rename the file. But here, special characters like "-" are NOT detected when you jump between the words via Ctrl-left / Ctrl-right.
For me, it is an important feature for organising my media

Just my 2 cent,
