在阅读Bash“ $ man bash”的联机帮助页时,我在(READLINE)部分中找不到某些选项的组合键

我是刚从联机帮助页学习的人,因此当我去查找用于编辑当前键入的命令的更多键组合时,例如

beginning-of-line (C-a)
Move to the start of the current line.

end-of-line (C-e)
Move to the end of the line.

我发现没有组合键的选项 例如

shell-forward-word ()
Move forward to the end of the next word. Words are delimited by non-quoted shell metacharacters.

shell-backward-word ()
Move back to the start of the current or previous word. Words are delimited by non-quoted shell metacharacters.

previous-screen-line ()
Attempt to move point to the same physical screen column on the previous physical screen line. This will not have the desired effect if the current Readline line does not take up more than one physical line or if point is not greater than the length of the prompt plus the screen width.

next-screen-line ()
Attempt to move point to the same physical screen column on the next physical screen line. This will not have the desired effect if the current Readline line does not take up more than one physical line or if the length of the current Readline line is not greater than the length of the prompt plus the screen width.

有什么我想念或愚蠢的无法理解的东西吗?

in this image example of what I say -look at yellow highlighted options-
