This is an annoyance that would be nice to fix:
-- Select a photo
-- Bring up the Keywords editor (K)
-- Move cursor to Keywords text edit box (Ctrl-Tab, or mouse)
-- Type a first keyword, hit enter to save it
-- Quickly type a second keyword, which contains letters that are keyboard shortcuts (e.g., "greg")
-- The second keyword appears in the Keywords text edit box
-- Your typing from the second keyword activates keyboard shortcuts. E.g., "G" activates Grid view, "E" switches to edit mode
-- The second keyword (e.g., "greg") does not appear in the Keywords text edit box
-- Wait a second before typing the second keyword, at which point the cursor will return to the Keywords text edit box.
-- This is annoying when you're trying to quickly enter a lot of keywords.
I'm using Adobe Lightroom version 4.3 on MacOS 11.4
