emacs - 如何在 evil-mode 下获得简单的导航窗口运动？

Question

在 vim 我的 .vimrc 中有这个:

" Easy window navigation
map <C-h> <C-w>h
map <C-j> <C-w>j
map <C-k> <C-w>k
map <C-l> <C-w>l

如何在 evil-mode 下获得简单的窗口导航？

另外，在 vim "+ 中会复制到我的系统剪贴板吗？这似乎在 emacs 中不起作用。

您可以将要使用的键绑定(bind)添加到 evil-normal-state-map :

(eval-after-load "evil"
  '(progn
     (define-key evil-normal-state-map (kbd "C-h") 'evil-window-left)
     (define-key evil-normal-state-map (kbd "C-j") 'evil-window-down)
     (define-key evil-normal-state-map (kbd "C-k") 'evil-window-up)
     (define-key evil-normal-state-map (kbd "C-l") 'evil-window-right)))

将代码包装成 eval-after-load有必要确保 evil-normal-state-map在调用 define-key 时定义/可用.

如果您想让相同的绑定(bind)在其他“状态”(例如“运动”状态)中也可用，只需将它们添加到相应的键映射中，如上所示(在“运动”状态的情况下，相应的映射是称为 evil-motion-state-map )。

要让 Emacs 使用系统剪贴板，请尝试设置 x-select-enable-clipboard到非 nil值(value):

(setq x-select-enable-clipboard t)

还有一些使用剪贴板的特定命令用于杀死和拉拽。从文档中:

clipboard-kill-region :

Kill the region, and save it in the X clipboard.

clipboard-kill-ring-save :

Copy region to kill ring, and save in the X clipboard.
