jEdit can automatically repeat keyboard commands, menu item selections and tool bar clicks any number of times you specify.
Pressing Control-Enter allows you to enter a number using the digit keys (0-9). The first non-digit character or command will be repeated that number of times. For example, "Control-Enter 1 4 Control-D" will delete 14 lines, and "Control-Enter 8 #" will insert the "#" character 8 times.
Most commands behave as expected when repeated, with one exception: if given a repeat count, the Edit>Go to Line command will move the caret to that line. If no repeat count is given, it will display the go to line dialog box.
