Most Windows applications map the keyboard's function keys to certain functions. In addition, the command console also supports function keys. Here's a summary of these function keys:

• [F1] does the same thing as the right arrow --> Adds the command previously issued one character at a time.
• [F2] displays a dialog box that prompts you to enter a character, and it copies the characters from the previous command up to, but not including, the entered character.
• [F3] copies all remaining characters from the previous command (much quicker than [F1]).
• [F4] is the opposite of pressing [F2]; it deletes all characters from the preceding command line up to, but not including, the entered character.
• [F5] cycles back through the previous commands, starting from the current location in the buffer (the currently displayed command); it pastes them to the command prompt but doesn't execute them.
• [F6] is the same as pressing [Ctrl]Z.
• [F7] displays a menu of the previous commands, allowing you to select and execute a command.
• [F8] cycles back through the previous commands, starting with the last command in the buffer; it copies the commands to the command prompt but doesn't execute them.
• [F9] displays a dialog box that prompts you for a buffer number; it copies the command in that line of the buffer to the command prompt but doesn't execute it.

By default, the console's command buffer holds 50 lines, but you can increase the buffer size up to 999 lines. Also by default, up to four console processes can have a unique buffer, but you can increase the number of processes up to 999. Click the console's Control button, and choose Properties to set the Buffer Size and Number Of Buffers properties.
