使用https://github.com/samoshkin/tmux-config主密钥是CTRL-a. 文档建议：
There is a root keybinding to enter Copy mode: M-Up. Once in copy mode, you have several scroll controls:
scroll by line: M-Up, M-down
scroll by half screen: M-PageUp, M-PageDown
scroll by whole screen: PageUp, PageDown
scroll by mouse wheel, scroll step is changed from 5 lines to 2
但按下时我无法让它工作CTRL-A + M-Page*
