My 2 cents worth... I'm betting on the "keyboard" - NOT the "mouse" - because the "mouse method" in many situations is SLOWER.
I agree it's nice to know about the "Control" key when "dragging and dropping", and you DON'T want any increment. Thanks, dianemarie!!!
HOWEVER, I have to agree with Skip... i.e. using Copy & Paste can be EASIER and FASTER - especially if one uses <Control> C for Copy, and <Control> V for Paste.
Steps:
1) Use <Control> C on the cell you want to copy.
2) Highlight the "Paste range" (hold down the SHIFT key, and use the DOWN Arrow key and/or PAGE Down key).
3) <Control> V.
I suppose it's always a "personal" thing, perhaps depending on one's "knowledge of the keyboard". However, one should not overlook the FASTER methods.
Hope this is a useful contribution.
