Zooming out

When I am viewing a pdf in DTPO, I can zoom in using ^apple+…but the reverse does not work to zoom out. I thought the shortcut was ^apple-…is that not right? The computer beeps when I do it and does nothing to zoom out. Thanks.

Option-Command-’-’ will zoom out and Option-Command-’+’ will zoom in, but as the ‘+’ character is the ‘=’ key shifted, the command is ‘Shift-Option-Command-’=’. I’ve changed the keyboard preference so that so that Option-Command-’=’ works as the zoom in.

Also, on a trackpad or Magic Mouse, pinch in/out gesture also works to zoom in/out.

Thank you!
