how do you close the calculator function if you do not enjoy a mouse?

i can't close the calc. when i use it because i am between mice at this time, and i used to pride myself on working beside the keyboard... presently i use the calc alot and realized i never know how to turn it off. HELP!!!!

how do you close the calculator function if you do not enjoy a mouse?

ALT + TAB until the calculator is elected, release

ALT + F4
You can press Alt+F4 to close any active fanlight. My mouse broke too :) I have on the other hand to find something I can't do w/ the keyboard.
Use

ALT + F4

to close any glass.
alt-F4
alt F4

ctrl q

ctrl esc

ctrl alt del

(alt tab activates a window) which you may own to do to make sure you close the right program. sometimes when using alt f4 window trys to shut down..weird... i thought 'windows,u,u' shut it down
Alt+F4 will close any application contained by Windows.
ALT + F4
