Remap select from t to ctrl+up/down

Question

I would like to change my current mapping

nnoremap t tj

to ctrl+up and ctrl+down to select the current element and move the pointer to the next or previous element, is this possible? I came up with

nnoremap [1;5A tk
nnoremap [1;5B tj

and while it select the current element and move the pointer correctly, it would not preserve the previous selection if I use the shortcut again, unlike the t tj mapping

edit: I solved by using av in visual mode instead

Answer 1

nnoremap  <esc>[1;5A tk
nnoremap  <esc>[1;5B tj

would probably be the correct mappings. When I enter the dash shell and do a Ctrl-down what I get is

$ ^[[1;5B

and ^[ is an escape.
