In IDA, how can you view the stack frame for a local function when IDA does not recognize any locals? Normally this would be done by double clicking on a local, but there is no local to start with. It's also absent from the 'Open Subviews' menu.
Although it doesn't appear to be documented anywhere (including in The IDA Pro Book) , I stumbled upon an answer: Ctrl+k. It was casually mentioned here.
It's also available in the menu Edit > Functions > Stack Variables
