Hi,
There are a couple of caveats with Tab Options's hotkeys:
- The hotkeys will not have any effect if some other part of the browser than the current web page has the keyboard focus. (See below for an explanation of keyboard focus, if needed.)
- The hotkeys will not have any effect if the keyboard focus is on a form field.
- The hotkeys will not have any effect if the current tab does not contain a web page.
Keyboard focus refers to what part of the browser "receives" a keypress. Different parts of the browser can have the keyboard focus. For example, if you have clicked inside the address bar, the address bar will have the keyboard focus. If you click inside the address bar and then press the Tab key, the keyboard focus will move to a button on the browser's toolbar. If you press Tab while the keyboard focus is on the last button on the toolbar, the focus will move to the first tab heading.
In order for Tab Options's hotkeys to work, the keyboard focus must be on the current web page itself. The easiest way to guarantee that the keyboard focus is on the web page is to click anywhere inside the page except a form field or button.
Fortunately, in general, unless you do something to move the keyboard focus off the web page, it will stay on the web page, even if you navigate to another page in the same tab.
The hotkeys will also not work if the current tab does not contain a web page. Things that could be in the current tab, aside from a web page, include the Favorites page and the History page, both of which are special Safari pages.
If the hotkey does not work even though you are sure that the keyboard focus is on the web page in the current tab, then one thing to check would be whether you might have assigned Option-Tab to some global hotkey, such as by using the Keyboard panel of System Preferences.
Hope this helps.
Chul
