BlinkMail, a new app form Yam Labs, has launched as a free download for Mac OS X. The app allows you to go through your in-box using only your keyboard’s arrow keys.
Just open your email client and you can customize the arrows to do whatever your want. You can set an arrow to delete the mail, archive it, reply to it, send it instantly to Evernote, shoot it over to Dropbox, place a label on the message, and more.
BlinkMail works with Mac OS X 10.9 (Mavericks) and higher. A premium version is coming soon for US$19.99. It will include the ability to aadd multiple accounts, reminders, and Evernote integration. Go to http://www.blinkmailapp.com for more info.
