This can be done via touch by tapping and holding on an item to select it, dragging to a new position and then releasing your finger. Selecting multiple file or objects can be achieved by tapping and holding to bring up a selection box and then drawing a box around the files before releasing the tap'' re:'' I can select all, but if i want to save one in a group, it deselects all the others.'' If you only want to save one email, then all others will be deselected because you do not want to save all. Not really a Thunderbird issue, but maybe someone using a touchscreen option may post something. Otherwise i would try asking about using touchscreens on the Windows forum. http://windows.microsoft.com/en-gb/windows/contact-support
