With $TERM='screen-256color' under tmux, HOME and END keys don't work. Why?
提问by jvc26
I have tmux set up with $TERMbeing set to screen-256colorcorrectly. This works fine, and colours are set correctly, however it prevents me from sending HOMEand ENDkeys to the terminal, which are instead printed as F\nand H\n.
我有TMUX设置了$TERM被设置为screen-256color正确。这工作正常，并且颜色设置正确，但是它阻止我向终端发送HOME和END键，而是打印为F\n和H\n。
I should add that home appears to work in irssi, but not vim. Home seems to send (According to Ctrl+v <HOME>), ^[OH
我应该补充一点，home 似乎在 irssi 中有效，但在 vim 中无效。家好像送（据Ctrl+v <HOME>），^[OH
It may be worth adding that I am well aware of the ability to use ^and $to move to the start and end of the lines, however $does not go to the end, rather the penultimate character, and I prefer to use HOMEand END(as I can under other $TERM settings).
可能值得补充的是，我很清楚使用^和$移动到行首和行尾的能力，但是$没有走到最后，而是倒数第二个字符，我更喜欢使用HOME和END（尽可能在其他 $TERM 设置下）。
Can anyone explain why this is, and how I can fix it?
谁能解释为什么会这样，我该如何解决？
As a part-way fix, I set the vim keybindings to map a <Home>and <End>keypress to <Esc>OHand <Esc>OF. This isn't ideal, but works for the moment! See https://github.com/jvc26/dotfiles/blob/master/.vimrcfor details.
作为部分修复，我将 vim 键绑定设置为将 a<Home>和keypress 映射<End>到<Esc>OH和<Esc>OF。这并不理想，但目前有效！有关详细信息，请参阅https://github.com/jvc26/dotfiles/blob/master/.vimrc。
Thanks!
谢谢！

The above mapping solution doesn't affect the command mode or visual mode. The following is a more ideal solution until either tmux or vim fixes the bug (put in your .vimrc):
上述映射方案不影响命令模式或可视模式。以下是一个更理想的解决方案，直到 tmux 或 vim 修复错误（放入您的.vimrc）：

if $TERM =~ '^screen-256color'
map <Esc>OH <Home>
map! <Esc>OH <Home>
map <Esc>OF <End>
map! <Esc>OF <End>
endif

It is also possible to set the keybindings in the .inputrcas explained on archlinux Home_and_End_keys_not_workingor .zshrcas on zshwiki/zle/bindkeys. This other stackoverflow question has some additional useful tips home-end-keys-do-not-work-in-tmux
另外，也可以设定键绑定在.inputrc作为上的archlinux解释Home_and_End_keys_not_working或.zshrc作为 zshwiki / ZLE / bindkeys。这个其他的 stackoverflow 问题有一些额外的有用提示home-end-keys-do-not-work-in-tmux
