Cannot type right curly brace in VIM For some reason, I cannot type right curly braces (}) in VIM. On my German keyboard, the shortcuts are &lt;ALT-8&gt; and &lt;ALT-9&gt; for left and right braces, respectively. These work in all applications, except for VIM, which does not recognize &lt;ALT-9&gt;.  

I use VIM 8 in iTerm2 on macOS 13.3. There are no plugins installed in VIM. None of the different :*map commands lists anything related to &lt;ALT-9&gt;.

How do I get my right curly brace back into VIM?
While checking the questions from @arcdale's comment, I found that &lt;ALT-9&gt; does not produce a } on the commandline, too. The cause of this was simply that I had mapped the navigation shortcut to switch panes in iTerm  to &lt;ALT-Number&gt;. Hence, binding switching panes to another combo solved the problem.

Howvever, this does not explain why there was a problem with &lt;ALT-9&gt;, while all the other combinations, &lt;ALT-5&gt; to &lt;ALT-8&gt;, worked as expected.
