To keyword photos in Lightroom, i like to use the keyword tags windows in the keywording panel. I like that i can type a few letters (mostly one or two) and a suggestion comes up; i can quickly just hit enter or pick another suggested one and hit enter. To add one, i just type ',' without even a space and type the next letter and so on... Then, without moving my hands from the keyboard, hit enter twice, then the right arrow key and i'm on the next photo. At this point i can't find a way to have the cursor active again for the new photo unless i move a hand to the mouse and click on the window! This is fine for a few pics, but for a few hundreds... It's irritating. For general keywords common to many pictures i use other methods, but sometimes to finalize the process and include a few keywords here and there unique to a picture this is working fine for me, other than this problem. Any help or suggestion very appreciated!
