MacOS – Rebinding “switch to next window” keyboard shortcut

You need 1Password v3.6.5 or newer to have single keystroke log in to work with Safari 5.1 (Lion or not)

It's on their FAQ - http://help.agilebits.com/1Password3/single_keystroke_login.html

If the System Preferences way of doing that doesn't work, the only other way I can think of remapping the command would be to use something such as Keyboard Maestro or TextExpander. Barring that, though (as they're both paid, third-party apps), there are still two ways to do navigate pages easily:

• Trackpad gestures

  This only works with multi-touch trackpads, such as the Apple-sold Bluetooth ones or the built-in-to-MacBook ones. Go to System Preferences > Trackpad > More Gestures and tick the "Swipe between pages" option. Set it to taste, and use that setting in Preview to switch pages.

• Page up/down keys

  If you have a full-size keyboard, you have page up/page down keys. If not, something that will probably work is using Fn + ↑/↓. This will scroll down and up by approximately one screen's worth. (Tip: Fn + left/right arrows act as Home/End keys.) If all else fails, space and shift-space do the same thing.
