explorer filebrowser, it is impossible to use keyboard accelerators F2/del within the treeview

0.4.11-RC-34-g5e059e7 gcc dbg linux affected

In the explorer filebrowser, in the treeview to the left.

Expected result
-Selecting a folder and pressing del key on keyboard should invoke delete
-Selecting a folder and pressing F2 key on keyboard should invoke rename

Observed result
-Both keys have no effect and do nothing, but both operations seem to be implemented,
-because delete-operation can be invoked properly via context menu
-rename operation can be invoked when clicking the folder a second time

Ros does not log anything, when I try with the accelerator keys, therefore I omitted the log here.
