New user, a couple of questions

Hi Guys
Currently using photomechanic but have found the latest version (6) to be slower and clunky compared to version 5 so im now trialing FRV, I have a few questions.
Is there a quick search function so I can imput a file number or multiple numbers and bring the images up and then drop in to a folder.
Is there a way to tag photos using the keyboard while scrolling through culling images, such as hitting the "T" key then when at the end have all the tagged images displayed so they can be dropped into a folder.
Is it possible to make sub folders on my desktop or external drive direct from the FRV interface, for instance clicking on "desktop" with a mouse in the left pannel and create a sub folder so I can then drag and drop selected images into the folder and move folders around from the left pannel, for instance drag and drop a folder from desktop to external drive.
One of the things I currently use photomechanic for is onsite printing, I use it on viewing screens and customers scroll through images tagging there favourites, I then create a folder and drop there selection in the folder so they are saved for them.  Then they select what they want printed from the favourites.
Best Wishes
Harry
