如何在tmux中为退出复制模式绑定自定义按键（如Esc）？

Absolutely you can bind the Esc key to exit copy-mode in tmux—this is fully configurable, even if that resource you checked didn’t explicitly list the command you needed. Here’s how to set it up:

• First, open your tmux configuration file (usually located at ~/.tmux.conf) in your favorite text editor. For example:

  nano ~/.tmux.conf
  

• Add this line to the file. This binds the Escape key to the command that exits copy-mode:

  bind-key -T copy-mode Escape send-keys -X cancel
  

  Let’s break this down:
  • bind-key -T copy-mode: Tells tmux we’re creating a binding that only applies when we’re in copy-mode.
  • Escape: The key we want to use for this action.
  • send-keys -X cancel: The underlying tmux command that exits copy-mode (this is what the default prefix+q is mapped to under the hood).
• Save the file and reload your tmux configuration to apply the changes. You can do this by running this command inside a tmux session (press your prefix key first, then type : to open the command prompt):

  source-file ~/.tmux.conf
  

Now, whenever you enter copy-mode (e.g., with prefix+[), pressing the Esc key will immediately exit you back to normal tmux mode. No need to use the prefix key first for this action anymore!
