Introduction

The tcsh Command Editor is perhaps the most important feature of tcsh not present in csh.

Notes

• The arrow keys of the terminal are set so that:
  • The up arrow moves to a previous command.
  • The down arrow moves to a more recent command.
  • The left arrow moves backward one character.
  • The right arrow moves forward one character.
• The simplest editing is to use the up arrow to review old commands to find the one that you want.
• The cursor will be at the end of the command.
• Use the left arrow to move left over characters.
• Pressing backspace instead of the arrow key will remove the character to the left of the cursor.
• Pressing characters will insert them into the line.
• Pressing the return key anywhere in the line executes the whole command line (you don't need to return to the end of the line when you're done editing).
• The bindkey command is the center of setup for command editor.
• bindkey with no arguments lists current bindings to commands (what editor command will be run when a given key is pressed).
• bindkey -l lists editor commands and a brief description of what it does.
• You can use bindkey to set your own bindings.
