我正在无头树莓派（牛眼）上使用nano中的lidssd1306。目标是允许通过 oled 显示屏上的编码器选择来执行 C 程序。
由于某种原因，在 Nano 中编辑文件时，
ctrl+shift+cctrl+shift+vCtl+6Alt+6(Ctl+K)Ctl+U我已经编辑了配置文件
/etc/nanorc~/.nanorcset mouse
bind ^X, ^C, ^V
这些都不允许我在文件之间复制/粘贴。
由于
ctrl+shift+cctrl+shift+vcatctrl+shift+vawk据此我推断必须存在隐藏/混淆的键绑定或设置。
允许在文件之间进行简单复制/粘贴的隐藏键绑定或设置是什么？
RasPi 靶心

答案是nano不支持人民币。有趣的是，它们支持按钮 4 和 5。也许有一天我会自己编写代码，我会将其添加到列表中...

* releases/clicks of the first mouse button. If allow_shortcuts is
* TRUE, releasing/clicking on a visible shortcut will put back the

* we also handle presses of the fourth mouse button (upward rolls of
* the mouse wheel) by putting back keystrokes to move up, and presses
* of the fifth mouse button (downward rolls of the mouse wheel) by
* putting back keystrokes to move down. We also store the coordinates
* of a mouse event that needs further handling in mouse_x and mouse_y.

假设nano在xterm上运行，只需常规的xterm键绑定即可轻松将系统剪贴板粘贴到nano中，例如通过Ctrl-Shift-V，即绕过nano的内部复制粘贴机制。所以那里没有问题。要从 nano 复制粘贴到另一个 nano 或其他任何地方，请将其放入 nanorc 中：
bind M-i "{execute}|xsel -ib{enter}{undo}" main
M-i 是 Alt-i（在我的键盘和许多其他键盘中）。使用 Alt 或 Ctrl (^i) 或 Shift-Alt (Sh-M-i) 放置任何未使用的键。如果使用的话，首先进入（进入nanoc）：
unbind M-i main
显然需要xsel或xclip包。
这个功能去年已经被引入到nano中了（我猜）。此机制的一些其他示例，用于全选并锚定您的位置以轻松返回，并将选择转换为大写/小写：
bind ^A "{anchor}{firstline}{mark}{lastline}" all
bind Sh-M-A "{anchor}" all
bind M-1 "{prevanchor}" all
bind M-2 "{nextanchor}" all
bind Sh-M-U "{nextword}{mark}{prevword}{execute}|sed 's/.*/\U&/'{enter}" main
bind Sh-M-L "{nextword}{mark}{prevword}{execute}|sed 's/.*/\L&/'{enter}" main
