Por fim, encontrei este artigo de blog descrevendo maneiras eficientes de marcar fotos no digikam .
Para facilitar a localização, aqui está o "método B", que permite usar o teclado apenas em toda a faixa de tags:
- select an album
- switch to "view image"-view (the bigger the picture, the better you can recognize the people, you want to tag)
- switch the right sideview to "Caption/Tags" and select tab "Tags"
- click in the uppermost input box, which shows the text: "Enter new tag here..."
- look for the leftmost person, you have not tagged yet
- start typing a few letters of the desired tagname (You have to start with the first letters in your tag name. There is no "mid word matching".) -> you will see a list of possible tags appear that shrinks with every letter you add to the input box
- if the list is reduced enough, use TAB to select the desired tag from this list
- hit ENTER to assign this tag to your picture
- if there are more persons, you want to tag, go to step 5 again
- if all persons on this image have been tagged, hit PAGE_DOWN to go to the next image and resume with step 5
Eu também poderia adicionar que uma opção que você receberá durante a digitação é adicionar a tag na tag atualmente selecionada. Perfeito:)
