The following procedures describe how to move the cursor on the screen:
The four arrow keys move the cursor in the direction of the arrow engraved on the key.
You can move the cursor past the edges of the box containing the text window. However, you cannot type in any area of the screen except the text window. If you continue to press the cursor movement key, the cursor moves to the opposite edge of the same line or column.
To move to the beginning of the line, press the Ctrl-A, Left Arrow key sequence (the Begin Line function).
The cursor moves to the first nonblank character on the current line. If the line is blank, the cursor moves to the left edge of the screen.
To move to the end of the line, press the Ctrl-A, Right Arrow key sequence (the End Line function).
The cursor moves one space to the right of the last character on the current line. It does not move the cursor to the right margin.
Press the Enter key (the Return function).
The Enter key operates much like the carriage return on a typewriter. However, the Enter key does not always place the cursor at the left margin of the next line. Pressing the Enter key places the cursor as follows:
Press the Ctrl-A, H key sequence (the Home function).
To move the cursor to the next tab stop, press the Tab key (the Tab function).
The editor sets tab stops for you. The t characters at the top of the editor screen are tab markers. You can set or remove tab stops.
In a tree-structured file, pressing the Tab key moves the cursor to the next field.
