The menu bar in Lightroom has a number of tabs, like Edit, Window, View, Photo, Metadata, etc. I can click on the tab to open them but I am trying to create a macro that starts by opening the Photo tab so my first command in Alt+P, which would ordinarily open the Photo tab, but it doesn't work. Alt+E, W, V, M, etc all work to open the respective tabs but Alt+P fails every time. I posted this question on my Lr forum and no else is having this problem. After I got their response I opened Lr on my desktop and it works on that machine every time. The first time I noticed this problem was a year ago and since then my IT service has run a "tune up" on my system several times and I have run regular system upgrades so I don't think there is a virus or malware issue. I have never, knowingly, remapped any keys on my keyboard. So why does this shortcut fail to work on my SB but not on my Desktop?
