I appear to have accidently hit a shortcut key which has activated annoying mode in excel. Now - if I focus on a cell (click on a box), when I hit the [Enter] key - the cell completes and the focus moves down to the next cell - thats all fine and dandy and working as expected. When I used the cursor keys up until around 10mins ago they used to move the focus around the cells on the sheet - e.g. hitting the UP button would select the cell above the current one. Now when I use the cursor keys all they do is pan the whole sheet around the open program - e.g. scroll up down left right without moving the Cell focus. Does anyone have any idea what I've enabled or disabled ? I've scoured the menus for a while now, but can't figure it out. Its happening to all spreadsheets I now open - so I'm pretty damn sure its an Excel (feature) Option.
