Vimperator Tip of the Day: Keys for Tabs

Tabs are mostly used in Firefox. Vimperator provides many convenient keys for tabs. In Vimperator’s term, buffer is used for tabs, ie, tabs are actually used as buffers to hold web pages. Here are some keys you can use for tabs or buffers:

Listing all tabs. :buffers, b or B. The difference between b and B is that B(:buffers) lists more defail information about buffers. % is used to indicate current buffer, and # for previous visited buffer. In case there are too many tabs opened, it is convenient to use these keys to find out buffer numbers.

Changing tabs. I use gt or gT most to change tabs. You can type buffer number before gt to jump directly to a tab.

If you have to switch between two tabs such as one for the current blog editting and another for blog preview, you may find out gb or gB very easy to jump between tabs. gb or gB is used to switch to previous :buffer commands.

Closing tabs. Use d to delete the current buffer or close the current tab. Use number before it to close count of tabs, including the current tab, to the right and the next right tab is selected. Use u to undo closed tabs.

By the way, Vimperator displays the current buffer or tab in the status bar like [num/tabs], where num is the tab number and tabs for total tabs:

Mac Tip of the Day: Log in Without Mouse

Mac is a graphics based OS system, you have to use mouse in most cases. Even though there some short-cut keys for quick access, not all the graphics items can be access by keys. However, I like to use keys instead of mouse if there is any way.

If you have set up users and password for Mac, you will see a log in window. You can use keyboard to make a selection by just typing the user name and then press enter key. After that, you just continue to type in your password.
