It's the last four entries made using the built-in editor,
regardless of what you edited; in ALG mode
you tend to include command arguments within each line,
as ALG syntax demands, whereas in RPN mode,
you are free to type all arguments followed by a command name
before completing an editor session, if you like,
but if you press ENTER after every individual
argument, then use a command key which acts
"immediately" (rather than editing its name),
you'll end up with argument items being saved individually.

Another RPN alternative is to enter algebraic expressions,
e.g. 'SIN(30)' and then EVAL them to get answers,
or to use a program which saves every function and its arguments
on the stack, so that you can repeat or edit it
just as in ALG mode, e.g.:

I think your opinion will be "seconded" by most readers here.

"Custom" menus are indeed a very nice (and probably under-utilized)
feature; the fact that in any directory not having its own
CST menu, the calc looks to higher directories to find one,
means that you can also put one universal "default" menu into HOME.

The automatic recording of every completed edit is automatic
(although it can be turned on/off in Menu 69, via a setting
which has no corresponding flag).

If you want command names to be inserted while editing,
you must do something which turns on "PRG" (program editing mode);
this mode is turned on automatically when you start entering
or editing a \<> or a {list} or a :tag:
but you can also force that mode at any time
via the R.S. ENTRY keyboard operation
(or by starting an edit using "Text Editor" in the APPS menu)

If you would also like to increase the number of saved entries
from just four up to hundreds, here's a program:

"Save unlimited command-line entries [HP49 version]"

"Save unlimited Last Commands [HP48 version]"

NOTE: You should make a memory backup *before* using these programs
(in case of harmful error in using "system" functions or their addresses).
