Navigate to a certain tab and close that tab in OSX Terminal I've got multiple terminal tabs open, and I want to be able to close the current tab. How can I make the current terminal tab be the active tab, so that I can close that tab with ⌘+w?

I am in the default Mac terminal.
In OSX Terminal, hold down the keys ⌘+Shift while arrowing right or left. This will allow you to switch between active tabs.

When on the tab you wish to close, as you noted, ⌘+w will close that tab.
