Nearly all editing operations happen at the location of the editing cursor. This cursor appears as a black block containing the base in a light colour, instead of the usual black base on a light background.
The simplest mechanism of moving the cursor is using the left mouse button. Alternatively the following keys can be used.
Left arrow or Control b Move left one base Right arrow or Control f Move right one base Up arrow or Control p Move up one base Down arrow or Control n Move down one base Control a Move editing cursor to start of sequence Control e Move editing cursor to end of sequence Home Move editing cursor to start of sequence End Move editing cursor to end of sequence Meta or Alt < Move editing cursor to start of contig Meta or Alt > Move editing cursor to end of contig
If any of these move the editing cursor outside of the visible region, the editor will scroll to accommodate. Control-a and Control-e with the editor on the consensus line will also jump to the start and end of the contig.
If "Cutoffs" are shown (see section Adjust the Cutoff Data) the cursor may be placed in the cutoff data too. Note that turning off displaying cutoff data would then leave the editor on an invisible base, so it is moved to the consensus line instead.
