3 Command Reference

3.6 Movement

This section gives details of commands used to move the current point (indicated by the cursor) around the buffer.

The use of prefix arguments with this set of commands can be very useful, as they allow you to get where you want to go faster. In general, using a negative prefix argument repeats these commands a certain number of times in the opposite logical direction. For example, the commandCtrl+U 10 Ctrl+Bmoves the cursor 10 characters backwards, but the commandCtrl+U -10 Ctrl+Bmoves the cursor 10 characters forward.

Some movement commands may behave slightly differently in different modes as delimiter characters may vary.
