Add Media/File description improvements for multi-selections feature

[stephdau]

This was suggested to us for WordPress.com by a coworker at Automattic and we realized this could actually be a worthy core improvement.

Would it be possible to add some wording to the Add Media screen in WP.com
blogs to tip users off that they can upload multiple images at once by holding
down CTRL in Windows or CMD on a Mac? Stumbled upon this nifty feature
myself today under the category of “here goes nothing, let’s see if this works.”

Opening the ticket until I can add a patch (or someone else does).

Because HTML5 supports multiple files too we should add some information.

3.3 for reviewing, related: #18206.

This seems simply enough. I'll try my hand at a patch for this.

[mikeschinkel]

Added note about uploading multiple files

[mikeschinkel]

Patch adds this line of text:

<strong>Note:</strong> You can select multiple images to upload by 
holding down the <kbd>CTRL</kbd> key on Windows or <kbd>CMD</kbd> on a Mac.

Newer patch based on verbal feedback from Nacin (so BlameNacin. :)

[mikeschinkel]

Added note about uploading multiple files, takes client OS into consideration.

[mikeschinkel]

This latest patch needs testing on Windows, Linux and something else that's not Mac as well as a non-OS X Lion Mac.

This is the sort of thing that would usually go in the help tab, because it would add clutter if it's there all the time. If someone posts a screenshot with patch applied I'll take a look, but might rather this be in help.

Attached screenshot and the refreshed patch.

BTW: Should the resize checkbox be on top? Looks lost there at the moment. Jane?

Not convinced on this. Looks like visual clutter and accounting for OS differences, it's a mess. Ultimately people may just end up selecting and dragging multiple files at this point.

It's not really WordPress' place to provide tips to people on how to use their OS. Unnecessary visual clutter, too.
