如何将字符键绑定到命令？像绑定之RIGHT seek +5类的，但使用字符键，如、a等。bc
更新
这答案（该问题被标记为与该问题重复）正在讨论配置键绑定，例如：
LEFT seek -5
RIGHT seek +5
我已经知道了。我在这里问的是不要使用LEFT或RIGHT作为键绑定。我问的是使用H或L作为键绑定。我试过这个：
H seek -5
L seek +5
并且不起作用。我知道该mplayer -input keylist命令没有列出任何字符键作为可用键。我在这里问的是：是否可以将字符键绑定到 Mplayer 中的命令？
答案1
快速答案是不，但是您可以编辑源代码或提出功能请求。
文档
mplayer中是这样说的：您可以通过运行获取受支持的键名称的完整列表
mplayer -input keylist，并通过运行获取可用命令的完整列表mplayer -input cmdlist。在我的计算机中

答案2
答案是可以的。将绑定放在名为的文件中~/.mplayer/input.config。这是我为您转储的文件（带有我的个人修改）：
##
## MPlayer input control file
##
## You are able to redefine default keyboard/joystick/mouse/LIRC bindings, or
## add new ones here.
## See DOCS/tech/slave.txt for possible commands that can be bound.
## Also see mplayer -input cmdlist for other possible options.
## The file should be placed in the $HOME/.mplayer directory.
##
## If you wish to unbind a key, use key ignore.
## e.g. ENTER ignore

## If you are using only the keyboard it is enough to define one command (like
## "menu up"), because then that single key will display the menu, which can
## then be navigated with the cursor keys and ENTER (defined in menu.conf).
##
## LIRC users should bind each "menu" command to a button on their remote.
##
## The set_menu command directly displays the (sub)menu specified as
## its argument. Usage should be self-explanatory (although not likely
## to be needed), after reading input.conf.
