List line numbers for easy navigation

[Heime]

I want to have a list of line numbers so that I can easily navigate to them
in the current buffer.

I would like to have a command that adds the current row to the list,
then have a command to move from one to the next, etc.  I frequently
have to navigate quickly between different parts of a buffer and need
some good commands to do this.

Is the current row the line at point?  If so, it's already in the list,
since the list contains all line numbers in the current buffer, isn't
that what you wanted?

To move from one line to the next? C-n. If that's not what you want, can
you rephrase?

What specifically do you mean by different parts?

To move cursor from one row in the list to the next row in the list.

Suppose I am writing some code at row 1358 and want to check on two functions,
one starting at row 355, the other at row 589.  I want to go to the row and add
the current row to the list (Will do this three times).  Then have a command to 
navigate between them.  Call command te get me to the respective row.

You can do this with existing Emacs commands: `M-g M-g' (or `M-g g') to
get prompted for a line number and then jump to it, and then you can use
the mark ring (info "(emacs) Mark Ring") or registers (info "(emacs)
Position Registers") to navigate between positions.  Why reinvent the
wheel?

Because I am finding that going to the marks with the current keybindings
difficult to remember.  Perhaps I can make a new easier command that takes 
care of the marks for me and help me use the existing emacs commands without
too much struggle.

Then I can only suggest reading those sections of the Emacs manual and
if necessary looking at the source code of the functions (I think most
of the are Lisp functions in simple.el).  Then maybe you can put
something together for yourself, though I suspect it won't be easy to
get something that works as well as the existing commands.  One other
tip: if what you really want to do is navigate between existing
functions or other named pieces of code, then using `M-.' and `M-,' is
probably the most efficient way, see (info "(emacs) Looking Up Identifiers").

I know that C-<SPC> calls the command (set-mark-command ARG)

But have no idea of the commands associated with "C-<SPC> C-<SPC>" and with "C-u C-<SPC>".  Would like a command I can
call with M-x that does the marking functionality.

Have done some code, but does not work very well

(defun tema-mark ()
  (interactive)
  (save-excursion
    (move-beginning-of-line nil)
    (set-mark-command nil)
    (move-end-of-line nil)))

(defun tema-move ()
  (interactive)
  (set-mark-command 1))

I would like the ability to name a line and then 
move to the named line.  What can I do ?

The words you are looking for are (info "(emacs) Position Registers")
and (info "(emacs) Bookmarks").
