Find any key with the help list
The pane has shown the key list, and now shows the clock.
C-b ? fills the pane with every key binding and what it does. Anything you find there you can press straight away, so there is nothing to memorise.
Down/C-Down- scroll the list
q- leave it
While the list is up the pane is in view mode: read-only, with its own keys that need no prefix. The top right corner shows your line number against the total.
Press C-b ?.
The pane fills with key bindings; the top right shows a line counter.
Scroll down with Down or C-Down until you find the row for C-b t.
It reads Show a clock.
Press q to leave the list, then C-b t.
A large clock fills the pane. Leave it there.
Three other ways to look a key up

Here is what just happened.
C-b ? runs list-keys -N and shows the result in view mode. C-b t runs clock-mode, which takes over the pane the same way; q leaves either mode. Every default key has a one-line description, so the list is the fastest way to find a key you half remember.
