how to navigate and select multiple files using only keyboard I would like to select multiple files non sequentially as in the illustration below...



On Windows I could simply hold down the Ctrl Key, navigate with Up and Down keys and hit the Space key to select or deselect a file.

But on mac if I hold down the Command key and hit Down arrow, it opens up the file (tested on images).
and ctrl + down arrow does something weird with the windows..

Is there any way to select such thing without mouse (which is way slower of course..)?
Unlike Windows MacOSX is not well designed for keyboard only access. There is no built in method for doing this. Sorry you're stuck with using the mouse in these situations.
