When I use the cursor keys or backspace/delete key to move the cursor in a text type field it takes for ever to move left or right and is jerky. This happens when I have the cursor in a Word doc, Excel cell, Safari and Chrome browser text boxes, Finder when editing a file name etc. It is really slow. The only way I can get the cursor to move faster is to keep tapping the keyboard delete key or a left or right cursor key. I have looked through Yosemite System Preferences but cannot find anyway to change the cursor movement speed, maybe I am missing the obvious. Even the Keyboard prefs do not seem to make a difference. Can anyone offer a solution? Thanks.
