The Vim debugger should give you a > prompt after displaying the command
which is about to be executed. At that point, you can use any Vim
command (such as :echo) to view the current values of variables etc
(except, I suppose, script-local variables). A colon is not required
unless you need to avoid ambiguity with one of the debug commands listed
below. Then you can give any of the following "debug-mode commands" with
*no* prefix (not even a colon) at the > prompt. The first letter is
enough, or you may type the full command:

cont
continue; don't stop unless a breakpoint is hit.

quit
quit Vim. Some breakpoints may be hit, some closedown
actions may be run.

next
execute one command and come back to the > prompt.
This doesn't stop inside functions and sourced scripts.

step
execute one command and come back to the > prompt.
If a function call is encountered, or a script sourced,
this stops at the first line inside the function or
script.

interrupt
don't continue the current command (as with Ctrl-C)
but come back to debug mode immediately afterwards

finish
continue to the end of the current function or script
then come back to debug mode on return to the caller

After a debug command has been given, hitting just <Enter> at the next >
prompt will repeat the same debug command.

For details, see ":help debug-scripts" and the full section 5 of that
helpfile.

Tertullian was born in Carthage somewhere about 160 A.D. He was a
pagan, and he abandoned himself to the lascivious life of his city
until about his 35th year, when he became a Christian .... To him is
ascribed the sublime confession: Credo quia absurdum est (I believe
because it is absurd). This does not altogether accord with historical
fact, for he merely said:

"And the Son of God died, which is immediately credible because
it is absurd. And buried he rose again, which is certain
because it is impossible."

Thanks to the acuteness of his mind, he saw through the poverty of
philosophical and Gnostic knowledge, and contemptuously rejected it.
