Suppose I have the following line in my command prompt and the cursor is at the and of the line or the beginning of the line by using (CTRL+A)[subhrcho@slc04lyo pcbpel]$ abc def ghi jklHow can I navigate to a particular word say, for example, to def. I am using tcsh shell in linux with default binding which I suppose is emacs mode.P.S:I do not have a Meta key in my keyboard. I can move forward or backward between words  by using CTRL+f and  respectively. So I think my Meta key is the Esc key. Please correct me if that presumption is wrong. Alt isn't working either as the meta key.I had a look at the emacs documentation but invoking CTRL-s w and then pressing Enter is not working for me. It would just try to execute whatever is there in the prompt by first appending a w character to it and the prompt would say :[subhrcho@slc04lyo pcbpel]$ abc def ghi jklwabc: Command not found.
In tcsh shell how I find a particular word in the command prompt?

By Meta-x tcsh means that it expects the ESC ASCII character (aka ^[ or \e) followed by x. You can always do it by pressing Escape and x quickly in sequence, or some terminals do it by pressing Alt-x.Some other terminals send the character x with the 8th bit set when pressing Alt-x. With xterm, you can change that by adding:XTerm*metaSendsEscape: trueto an X11 resource file.Now, for searching in tcsh, if you want to emulate emacs/zsh Ctrl-R or Ctrl-S in emacs mode, you'll have to bind the i-search-back and i-search-fwd widgets:bindkey '^R' i-search-backbindkey '^S' i-search-fwdHowever note that generally, for the terminal driver, ^S is the stop character that pauses the terminal input and output (resumed with ^Q). So, if you want to bind ^S, you'll have to disable that either by disabling flow control:stty -ixonOr bind stop to some other character:stty stop '^T'
