Helix save cursor position (manual workaround)

Just do it

Script that we call from helix and it stores the current line (hxsaveline):
https://raw.githubusercontent.com/brontosaurusrex/bucentaur/refs/heads/master/.experiments/bin/hxsaveline

Entry in your config.toml that binds alt+w to save current line via hxsaveline script (under [keys.normal]):

"A-w" = ":sh hxsaveline %{buffer_name} %{cursor_line}"

Wrapper that will read the stored line and open helix (hxw):
https://raw.githubusercontent.com/brontosaurusrex/bucentaur/refs/heads/master/.experiments/bin/hxw

so you open your file as

hxw yourfile

and it should open with cursor on stored line.

How about just reading and displaying stored line inside helix, this script (hxloadline):
https://raw.githubusercontent.com/brontosaurusrex/bucentaur/refs/heads/master/.experiments/bin/hxloadline

and in your config.toml we will use free alt+l (under [keys.normal])

"A-l" = ":sh hxloadline %{buffer_name}"

will just print stored line number and do nothing else, but one can 18gg or :g 18.

This is experimental workaround that will not work in all conditions and ‘should’ really be a core editor feature imho.

Recap

You have 3 new little shell scripts somewhere on $PATH: hxloadline, hxsaveline, hxw and something like this added to your config.toml under [keys.normal]

# save cursor position with ctrl+w via small bash script
"A-w" = ":sh hxsaveline %{buffer_name} %{cursor_line}"
# load cursor position and do nothing with it via small bash script
"A-l" = ":sh hxloadline %{buffer_name}"

And you can use hxw instead of hx to load your files positioned on the stored line. Or use alt+l to display stored line and then :g 42.

btw

The issue goes deeper, undo history, command history, etc.

and true colors in tmux, .tmux.conf, add:

set -g default-terminal "tmux-256color"
set-option -sa terminal-overrides ",xterm*:Tc"

Fzf preview mine

Mine

Something like that in .zshrc

# making FZF to look like my fancy note script
# Black & white - explicitly disable all colors
export FZF_DEFAULT_OPTS="--no-color --pointer='>' --color=fg:-1,bg:-1,hl:-1,fg+:-1,bg+:-1,hl+:-1,info:-1,prompt:-1,spinner:-1,pointer:-1,marker:-1,border:-1"

# CTRL-T command - recent files first
export FZF_CTRL_T_COMMAND='find . -type f -not -path "./.git/*" -printf "%T@ %P\n" 2>/dev/null | sort -nr | cut -d" " -f2-'
# or faster find with fdfind
# export FZF_CTRL_T_COMMAND='fdfind . --type f --hidden --exclude .git --strip-cwd-prefix -x stat -c "%Y %n" {} \; 2>/dev/null | sort -nr | cut -d" " -f2-'

# Preview configuration
export FZF_CTRL_T_OPTS="
  --no-color
  --prompt='file> '
  --pointer='>'
  --marker='*'
  --bind='tab:toggle'
  --preview='fzf_preview_mine {}'
  --preview-window='right:50%:wrap:noinfo'
  --height=80%
  --reverse"

And the preview script fzf_preview_mine. Should handle a subset of txt, epub, pdf, video, audio, image files as 2nd pane fzf preview. Needs sixels and some apps like: ffmpeg, mediainfo, mpv, chafa, imagemagick convert (psd), inkscape (svg), atool (preview archives) …

tested with

Chafa version 1.18.2
fzf 0.60 (devel)

Newer might be fine.
