-===== Command line Editing ===== 
- 
-The command line works like a single-line word processor, allowing you to edit any part of the command at any time before you press **Enter** to execute it, or **Esc** to erase it. The command line you enter can be up to 1023 characters long.  
- 
-You can use the following editing keys when you are typing a command (the words **Ctrl** and **Shift** mean to press the Ctrl or Shift key together with the other key named):  
- 
-==== Cursor Movement Keys: ==== 
- 
-|**<-**  |Move the cursor left one character. | 
-|**->**|Move the cursor right one character. | 
-|**Ctrl+<-** |Move the cursor left one word. | 
-|**Ctrl+->** |Move the cursor right one word. | 
-|Home    |Move the cursor to the beginning of the line. | 
-|End       |Move the cursor to the end of the line. | 
- 
-==== Insert and Delete: ==== 
- 
-|Ins  |Toggle between insert and overtype mode. | 
-|Del |Delete the character at the cursor. | 
-|Backspace  |Delete the character to the left of the cursor. | 
-|Ctrl-L  |Delete the word or partial word to the left of the cursor. | 
-|Ctrl-R or Ctrl-Bksp  |Delete the word or partial word to the right of the cursor. | 
-|Ctrl-Home |Delete from the beginning of the line to the cursor. | 
-|Ctrl-End |Delete from the cursor to the end of the line. | 
-|Esc  |Delete the entire line. | 
- 
-==== Execution: ==== 
- 
-|Ctrl-C or Ctrl-Break |Cancel the command line. | 
-|Enter |Execute the command line. | 
- 
-Most of the command-line editing capabilities are also available when a **CMD.EXE** command prompts you for a line of input. For example, you can use the command-line editing keys when [[DESCRIBE]] prompts for a file description, when [[INPUT]] prompts for input from an alias or batch file, or when [[LIST]] prompts you for a search string.  
- 
-If you want your input at the command line to be in a different color from **CMD.EXE**'s prompts or output, you can use the Display page of the [[OPTION]] dialogs, or the [[InputColors]] directive in //CMD.INI//.  
- 
-**CMD.EXE** will prompt for additional command-line text when you include the [[escape character]] as the very last character of a typed command line. The default escape character is the caret [^]. For example:  
- 
-<code> 
-        [c:\] echo The quick brown fox jumped over the lazy^ 
-        More? sleeping dog. > alphabet 
-</code> 
- 
-Sometimes you may want to enter one of the command line editing keystrokes on the command line, instead of performing the key's usual action. For example, suppose you have a program that requires a Ctrl-R character on its command line. Normally you couldn't type this keystroke at the prompt, because it would be interpreted as a "Delete word right" command.  
- 
-To get around this problem, use the special keystroke **Alt-255**. You enter **Alt-255** by holding down the **Alt** key while you type **255** on the numeric keypad, then releasing the Alt key (you must use the number keys on the numeric pad; the row of keys at the top of your keyboard won't work). This forces **CMD.EXE** to interpret the next keystroke literally and places it on the command line, ignoring any special meaning it would normally have as a command-line editing or history keystroke. You can use **Alt-255** to suppress the normal meaning of command-line editing keystrokes even if they have been reassigned with [[key mapping directives]] in the //.INI// file, and **Alt-255** itself can be reassigned with the [[CommandEscape]] directive.
