How can you tell what commands you've typed recently

:his

:his[tory] Print the history of last entered commands.
{not in Vi}
{not available when compiled without the |+cmdline_hist|
feature}

:his[tory] [{name}] [{first}][, [{last}]]
List the contents of history {name} which can be:
c[md] or : command-line history
s[earch] or / search string history
e[xpr] or = expression register history
i[nput] or @ input line history
d[ebug] or > debug command history
a[ll] all of the above
{not in Vi}

If the numbers {first} and/or {last} are given, the respective
range of entries from a history is listed. These numbers can
be specified in the following form:
*:history-indexing*
A positive number represents the absolute index of an entry
as it is given in the first column of a :history listing.
This number remains fixed even if other entries are deleted.

A negative number means the relative position of an entry,
counted from the newest entry (which has index -1) backwards.

Examples:
List entries 6 to 12 from the search history: >
:history / 6,12
<
List the recent five entries from all histories: >
:history all -5,

Also, your / register contains the LAST thing you searched for
