Folks accustomed to number lock may have a hard time moving from an Apple extended keyboard to the more compact keyboard layout found on Apple##Q##s wireless keyboard or its MacBook models. If you can##Q##t live without num lock, then you should check out the NumLock app, a Kickstarter-funded app from developer Dennis Vogel.
NumLock runs in the background and provides you with a hotkey combo or menu bar item that##Q##ll toggle NumLock on and off. When enabled, NumLock lets you use the 7-8-9, u-i-o, j-k-l and m-,-. keys as a numeric keypad.
Vogel already has a working version of the app and has turned to Kickstarter to help fund some of his early development costs. If he reaches the $574 Kickstarter goal, the app will be released as freeware. You can read more about NumLock on the app##Q##s Kickstarter page. The Kickstarter project already has a few backers and will end on Thursday April 4th, 11:47 AM EDT.
