I have read dozens of posts about moving the cursor. All of them use the word cursor instead of the correct word pointer. The arrow-shaped pointer indicates mouse position. The vertical line cursor (that usually blinks) indicates the active position between text characters. A cursor always exists at the same time as a pointer, but they are not usually in the same location.
So, given the correct definitions above, does anyone know how to change the cursor position in a text document, preferably without moving the pointer?
At the risk of being obvious, there are also other keystrokes that will navigate within most text documents:
Up/Down-Arrow will move the cursor line by line.
Option-R/L Arrow will move the cursor word by word.
Command-R/L Arrow will move the cursor to the beginning or end of a line.
Command-Home/End will move the cursor to the beginning or end of a document.
Please be more specific about what you're trying to do.
Apple has provided very little direct control over the text cursor, but there are various work-arounds – some that are fairly universal – and some that are very app-specific like in BBEdit.
