Pressing TAB again selects the second item and replaces the -;; "inserted" item with the second one. This can continue as long as the user -;; wishes to cycle through the menu. You can also press S-TAB to select the -;; previous candidate, of course. -;; -;; The benefits are that you only have to use one shortcut key and there is no -;; need to confirm the entry. -;; -;; Usage: -;; -;; To apply the default configuration for company-tng call -;; `company-tng-configure-default' from your init script. -;; -;; You can also configure company-tng manually: -;; -;; Add `company-tng-frontend' to `company-frontends': -;; -;; (add-to-list 'company-frontends 'company-tng-frontend) -;; -;; We recommend to bind TAB to `company-select-next', S-TAB to -;; `company-select-previous', and unbind RET and other now-unnecessary -;; keys from `company-active-map': -;; -;; (define-key company-active-map (kbd "TAB") 'company-select-next) -;; (define-key company-active-map (kbd "<backtab>") 'company-select-previous) -;; (define-key company-active-map (kbd "RET") nil) -;; -;; Note that it's not necessary to rebind keys to use this frontend, -;; you can use the arrow keys or M-n/M-p to select and insert -;; candidates.
