As a previous Windows user, when I want to select a bunch of files that are in a row (but not all), I click the first one, then Shift-click the last, and all in between are selected. Everything I have read has indicated that this should be the same in Yosemite on my iMac. But no. On that computer, Shift acts like Control, I can individually select files and they stay selected for copying or moving or whatever, but if I select the first, press/hold Shift and select the last in my list, I have 2 files selected, and when I copy them, only those 2 files copy. Is the use of Shift like that some sort of setting somewhere? Thanks in advance. This is a pain when having to select more than 30 files to copy.
