Efficient photo tagging with digikam

Hello, I have tried to use the method “B” on digiKam 5.5.0 but it did not work as described.

Everything works until the next step.

7 if the list is reduced enough, use TAB to select the desired tag from this list

Pressing TAB brings me to the tags search field at the bottom of Tags Tree.

8 hit ENTER to assign this tag to your picture

Nothing happens after that. I tried pressing SPACE too.

9 if there are more persons, you want to tag, go to step 5 again
10 if all persons on this image have been tagged, hit PAGE_DOWN to go to the next image and
resume with step 5

PAGE DOWN does not work neither from the “enter tag here” box nor from the tags search box. (“from” means that the cursor is currently in that field). It does work if I click on the tags tree first but now the method is not keyboard only anymore.

Keyboard focus will always stay in the tag input box. So you can keep your hands on the keyboard all the time and tag very fast.

This did not work either.

Can someone to take a look at this and let me know if there is something I am doing wrong here?
