How do I configure a keybinding for `<` and `>`

galou · October 25, 2024, 5:36pm

In config.json5 I can configure keybindings such as <q>": "Quit", // Quit the application.

How do I configure a keybinding for < and >?

I tried:

"<'<'>"
"<\\<>"
"<\<>"
"<<>"
"<"
and don’t know what to try next.

Thanks!

<Shift-,> and <Shift-.> maybe?

Thanks for the quick answer!

<Shift-,> parses OK but doesn’t work (has no effect) but <Shift-.> doesn’t parse.

Anyway, this would not be a solution because this would work only on US keyboards (and keyboards that have the same layout for these keys).

I’d guess that it probably isn’t supported, but the code for this is generated into your app, so you should in general be able to make this work. Check e.g.:

github.com

ratatui/templates/blob/main/component-generated/src/config.rs#L294-L319


      
          pub fn parse_key_sequence(raw: &str) -> Result<Vec<KeyEvent>, String> {
              if raw.chars().filter(|c| *c == '>').count() != raw.chars().filter(|c| *c == '<').count() {
                  return Err(format!("Unable to parse `{}`", raw));
              }
              let raw = if !raw.contains("><") {
                  let raw = raw.strip_prefix('<').unwrap_or(raw);
                  let raw = raw.strip_prefix('>').unwrap_or(raw);
                  raw
              } else {
                  raw
              };
              let sequences = raw
                  .split("><")
                  .map(|seq| {
                      if let Some(s) = seq.strip_prefix('<') {
                          s
                      } else if let Some(s) = seq.strip_suffix('>') {
                          s
                      } else {
                          seq
