I'm looking for a keyboard shortcut in tcsh to move the cursor back to the previous blank: not ESC+B which takes me back one word (for instance, in a path argument, to the previous path component) - I want to get to previous space or start of current path.

If you mean keyboard shortcut at the prompt of interactive bash shells, you could bind the shell-backward-word and shell-forward-word to some sequence of characters sent upon some key or combination of key presses.

Like if pressing Ctrl-Left sends the sequence e[1;5D on your terminal like it does in xterm, you could do:

bind '"e[1;5D": shell-backward-word'
bind '"e[1;5D": shell-backward-word'

Note that it does not jump from blank to blank but considers shell quoting. So for instance in a line like

echo "foo 'bar baz' blah/bleh bloh
^ ^ ^ ^

It would jump to the locations marked above.

Edit: for tcsh, you have three options:

1. 
   

   Use the equivalent to the bash definition above, either in ~/.cshrc or in /etc/csh.cshrc.local to give all users the benefit.

   
   
   

   bindkey 'e[1;5D' backward-word
   bindkey 'e[1;5C' forward-word
   

   
   



2. Use the vi mode (with bindkey -v) and use the B and W keys in normal mode just like in vi.



3. 
   

   In emacs mode (the default, reenabled with bindkey -e) like for bash, bind the corresponding widgets (vi-word-back and vi-word-fwd):

   
   
   

   bindkey 'e[1;5C' vi-word-fwd
   bindkey 'e[1;5D' vi-word-back
   

   
   

Note that those are like vi's B and W, so they're for jumping between blank separated words, not shell tokens (like quoted strings) like in the bash solution above.

I think you're wanting CTRL-B which in bash moves the cursor back one character. CTRL-f will then move you back forward. Here is a quick reference for these shortcuts.

"ESC-left-arrow : go to beginning of left word"
bindkey ^[^[[D vi-word-back

for example:
cd a/b/c/d
ESC+left will take you from end of line to the space between "cd" and "a"
