Here's a cool tip for all Gmail-ers.
You may now attach multiple files at once to your outgoing emails.
Quoting Gmail blog,
"If you want to send a few files from the same folder, simply hold down the Ctrl key (Cmd on OS X) and click on each file you want to attach to your message. You can also hold down the Shift key to select a continuous list of files. A definite time saver."
A time saver, indeed! Thanks Gmail!
