Re: [External] : Q3 - how to delete by words, not cut?

[Tatsu Takamaro]

   *Did you try the `my-backward-delete-word' command I defined for you?*

Sorry, I didn't try it before. Because I didn't understand it by that 
time (and I have a habbit not to run any code until I understand it good 
enough). But now I dived into it and got it...
Though the function logic is clear, the key binding won't work. I tried 
different keys. Here is the current state:

       *(defun tt-delword-backward (arg)**
       **"Delete backward arg words. (default 1)"**
       **(interactive "C-;")**
       **  (let**
       **  ((opt  (point)))**
       **  (backward-word arg)**
       **  (delete-region opt (point))**
       **  )**
       **)**
       **
       **(defun tt-delword-forward (arg)**
       **"Delete forward arg words. (default 1)"**
       **(interactive "C-'")**
       **  (let**
       **  ((opt  (point)))**
       **  (forward-word arg)**
       **  (delete-region opt (point))**
       **  )**
       **)*

I tried to set (interactive "b") and (interactive "f") for backward and 
forward respectively. When "C-;" is set the minibuffers says it's 
undefined, when letters are set it just type letters. The call by M-x 
doesn't do the job either.
