Holding alt and something else also typically sends escape, for example holding alt+a will send an escape character and then an "a".
fish waits for a period after receiving the escape character, to determine whether it is standalone or part of an escape sequence. While waiting, additional key presses make the escape key behave as a meta key. If no other key presses come in, it is handled as a standalone escape. The waiting period is set to 30 milliseconds (0.03 seconds). It can be configured by setting the ``fish_escape_delay_ms`` variable to a value between 10 and 5000 ms. This can be a universal variable that you set once from an interactive session.
So the escape character has its own timeout configured with :envvar:`fish_escape_delay_ms`.
