问题
Xcode offers several key codes to open the Find (CMD-F) or Find and Replace (CMD-OPT-F) editor toolbar, but how can I get the Find Options to show without having to move my mouse over the magnifying glass and clicking (which takes forever, I misclick, and then have to select the menu item - ugh)?
回答1:
I have not found a single key to do this, but just discovered that after using CMD-F or CMD-OPT-F that the Find search field has focus, and by tapping the down arrow key twice followed by a Return key, that it opened (do again to close)!
I added a key code sequence to Butler so I can use a single key to do this, so use your favorite Macro program to do likewise.
EDIT: Just discovered this still works in Xcode 7, you just need to do 2 down-arrows followed by a return.
