questions around vim functionalities

Hi,

I have been redirected here from https://github.com/xonsh/xonsh/issues/4292 .

From the discussions there:

"

• some vim commands are not available; for example, if I do 10 a - ESC, that only inserts one -, not 10
• it is only possible to navigate the current prompt line, not what is above. For example, in a situation like:

$> some_command
some_interesting_output_1 some_interesting_output_2
$> my_prompt_is_here

I cannot navigate in vim-mode to copy some_interesting_output_2 as if the whole terminal was a single file that I navigate with vim; any idea if this is attainable? :)
"

I was wondering: are these limitations of the present repo (and if so, could the functionalities be added?), or is it a limitation of how Xonsh uses the prompt-toolkit? :)

Start with the linked xonsh issue 4292 and this discussion to separate missing Vim commands from terminal-history navigation. The issue names no files or tests, so define the desired behavior and identify the prompt-toolkit Vim-mode entry points before estimating implementation or verification work.
