Mapping ESC in minibuffer normal mode to keyboard-quit and autoindent woes

I like to have ESC behave like C-g in normal mode in the minibuffer, I've tried to no avail: (vimpulse-map (kbd "ESC") 'keyboard-quit) (define-key viper-minibuffer-map (kbd "ESC") 'keyboard-quit) Another issue is vimpulse messing with comment indenting. I have RET bound to comment-indent-new-line so that in a comment, pressing enter inserts a comment prefix. However, with vimpulse on, it inserts an extra tab to the new line. Eg. Initially in insert mode, cursor at | //| RET // //| RET // // //| RET // // // //| .. Any help is greatly appreciated!
