Do you Alt-Tab?

Most of the time I do my office work from my home.So this question doesn't arise for me.

i didn't know about that special keyboard function! its good to know something new. well for me, i always minimize whatever window is open in my computer when i leave it. i don't really want my officemates especially my boss to see whatever it is i'm doing in the internet. although mostly i just check my mails in the office and its no big deal if someone sees it. but i just don't want them to think that i'm always internet surfing when i'm at the office.

Yes i close my all open files when my boss come to me.but when my other coleags come to me i just minimiz them.and starts again when they leave
