Perla-rt

THanks, I am using a Macbook Air, thanks, I did with CRTL + ALT + T in one of my notebooks and it worked well. I am the owner of this notebook. However, I cannot do it in the other one, I didn't create the notebook, it was shared with me, but I don't have permission to add the tags. I have permission to edit, add new notes, and move them to another notebook, however, I cannot add the tags, should I be the owner to add the tags? Please see the screenshot below, at the bottom of the screenshot, the blue menu, doesn't allow me to select the tag option.

Hi, I have a compilation of about 4000 notes. I wonder if it is possible to add tags in bulks to these past notes. I wanted to select several notes at once to tag them in a bulk, but it was not possible. I wonder if that is a way to do this. Adding tags one by one will be a pain in the ass. Thanks
