text within documentyou must fill the document with blank lines and spaces as necessary the minimum cursor movements available with most text editors includevertical movement in which the cursor is moved one or more lines up or down from the current line when the cursor is moved in the vertical directionit typically maintains the same character position on the line to which it was moved if this line is shorter than the one from which the cursor was movedthe cursor is typically positioned at the end of the line horizontal movement along the current line in which the cursor moves either forward or backward when the cursor reaches the beginning of the lineit wraps backward to the end of the previous linewhen it reaches the end of the lineit wraps forward to the beginning of the next line thusthe cursor moves about the text document as if moving within stream of text like that stored in text file movement to the document and line extremes the cursor can typically be moved to the front or back of the current line or to the beginning or end of the document in the latter casethe cursor is typically moved to the front of the last row in the document inserting text most text editors use an entry mode of either "insert,in which new characters are inserted into the textor "overwrite,in which new characters replace existing characters in either modecharacters are inserted into the document at the cursor position when using insert modeall characters on the same line from the cursor to the end of the line are shifted down and the new character is inserted at the current position this differs from overwrite modein which new characters simply replace or overwrite the character at the cursor position in both casesthe cursor is then shifted one position to the right on the same line the newline characters that are used to indicate the end of line can be treated like any other character if new characters are inserted immediately before newline characterthe line is automatically extended when inserting text after newline characteryou are technically inserting the text at the beginning of the next line in front of the first character on that line when newline character is inserteda line break is created at the insertion pointresulting in the current line being split into two lines the new line is always inserted immediately following the line being split deleting text most text editors provide both delete and rub-out operation for removing individual characters from document these are typically mapped to the delete and backspace keysrespectively both operations delete character and shift all following characters on the same line forward one position the difference between
