Comment 2 for bug 1331103

Hi Jeremy. You're right, I'm talking mainly about keyboard shortcuts, but I wanted to review the whole mechanism.

Using the mouse, you have and indicator on the context menu "paste / paste into" (still subtle at the point I did not noticed it the first time, but its there), but using the keyboard you have nothing to pre-discover this behaviour, and nothing to post-discover it. You have no feedback.

Unless you're pasting a very big chunk of files (the progress indicator pops-up), the "paste-into" action take place silently and hides the data from the user. The copy/paste mechanism was never reliable (on a multitasking environment, the clipboard gets easily overridden), and you must go inside the subfolder to acknowledge the action. The user can easily assume something is wrong and the action did not take place. That can leave sensitive information on inconvenient places, like the public folder on Dropbox, or cut the data from the original folder, and hide them somewhere on the user navigation history.

So, my point: using the keyboard the action is not discoverable, but suing the mouse is also not evident enought to be a reliable method to deal with user's data.

The obvious solution could be to add some visual feedback, say, an animation on the target folder. That work is you have eyesight. If not, the screen reader supposedly told you that action is named "paste into folder" and not "paste", assuming you are using the context menu.
Also, a "turn off" switch could be welcome. I use several OSs and it is difficult to not intuitively paste things without noticing the selected folder.

What do you think?
