Hi Dorin

thanks for this information

the obvious question remains - why is this simple fundamental info not in the User Guide and/or obvious easy place?

SHIFT for multiple select is a standard, as is CTRL to selct/deselect individual item

so why is SHIFT-Select not Select/Deselect all? and CTRIL+Select Deselect current one

SHIFT for both multiple select AND for Deselect is both inconsistent and confusing

but i thank you for this basic information
