Sublime文本键盘快捷键绑定不起作用

按照此处的说明，我已经安装了SublimeText的新安装以便与R一起使用。我没有安装其他SublimeText插件。使用上方链接中的说明设置的键盘快捷键不起作用。我已经按照教程中的说明设置了用户密钥绑定文件。

“默认”键绑定文件中没有冲突的键绑定。

尽管如此，我可以通过单击菜单在REPL中执行我的R代码：

工具> SublimeREPL> REPL中的评估>选择（Ctrl+ Shift+ R）

如果我实际按下Ctrl+ Shift+ R快捷方式，则什么也不会发生。

这是我的用户密钥绑定文件的副本：

// Executes line(s) of text in REPL terminal, latter only displays code and does not execute
{ "keys": ["ctrl+alt+r"], "command": "repl_transfer_current", "args": {"scope": "lines"}},
{ "keys": ["ctrl+alt+r", "r"], "command": "repl_transfer_current", "args": {"scope": "lines", "action":"view_write"}},

// Executes a block (e.g., a custom function) of text in REPL terminal, latter only displays code and does not execute
{ "keys": ["ctrl+shift+alt+r"], "command": "repl_transfer_current", "args": {"scope": "block"}},
{ "keys": ["ctrl+shift+alt+r", "r"], "command": "repl_transfer_current", "args": {"scope": "block", "action":"view_write"}}

]

我究竟做错了什么？

这有一个简单的解决方案。配置文件中有错误，只需删除shift + ctrl + r，r行即可：

// Executes line(s) of text in REPL terminal, latter only displays code and does not execute
{ "keys": ["ctrl+alt+r"], "command": "repl_transfer_current", "args": {"scope": "lines"}},


// Executes a block (e.g., a custom function) of text in REPL terminal, latter only displays code and does not execute
{ "keys": ["ctrl+shift+alt+r"], "command": "repl_transfer_current", "args": {"scope": "block"}},

感谢OP的以下评论：

好吧，这很奇怪。如果我按ctrl + shift + CapsLock + R，它可以正常工作...

我可以猜测这["ctrl+shift+r"]会等待小写r，但是，当您按下shift键（这是快捷键组合的一部分）时，它会读取大写字母R。

当OP打开CapsLock时，r通常会输出按R，但是在SHIFT按键的情况下会显示小写字母r。

这可能是因为Sublime尝试读取完全相同的字符，而不是按下按钮的键代码。

因此，解决方案应该在键组合中使用相反的大小写字母，包括SHIFT（在这种情况下使用R代替r）：

// Executes a selection of text in REPL, latter only displays code and does not execute
{ "keys": ["ctrl+shift+R"], "command": "repl_transfer_current", "args": {"scope": "selection"}},
{ "keys": ["ctrl+shift+R", "r"], "command": "repl_transfer_current", "args": {"scope": "selection", "action":"view_write"}},
