Key Remapping hjkl ~~> jkl; Fails in multiple ways in Normal & Select mode

[dream-dasher]

Summary

[Note: I'm posting this as it indicates a bug not because I have an issue with it, specifically. I am no longer using the shifted mapping, but the fact that shifted mapping fails so inconsistently is, ofc, notable]

Remap: (hjkl~~>jkl; && ; ~~>h)
A config.toml with notes and images of same with failed remappings highlighted is attached.
The nature of the failures is not consistent.
Sometimes the hjkl behavior is retained.
Sometimes no effect is produced.
Sometimes it's for one direction and not another where as sometimes its for all directions.
And 'Visual' mode no longer highlights with direct arrow movement keys.

Example failing config.toml file (Note: remove the .txt at the end -- had to postpend that to get github to load it & and of course remove the description pre- config.toml)
failing_key_remapping-config.toml.txt

Reproduction Steps

Highlighted and annottated remapping images attached.
The config.toml file also attached so one can just switch that in and drive it themself.

While we're on the topic, I have found it impossible to remap . (the dot). It just will not map to what I set it to.

Repeat last insert . is a separate issue: #1488

For most of these, this is a limitation of TOML. Each successive table is overwriting the last instead of being merged.

You have to use a single table for all sub-keys:

[keys.normal]
z = { k = "scroll_down", l = "scroll_up" }

Or use:

[keys.normal.z]
k = "scroll_down"
l = "scroll_up"

For the "doesn't work (doesn't select text, but does move)" ones, this is expected behavior. Use extend_* commands (extend_char_left/extend_line_down/extend_line_up/extend_char_right) instead of move_* to keep the selection as you move.

Made those changes and everything works. So this was a TOML-syntax (+ one bit of Helix-semantics) issue.
Thanks.

Very unfortunate (read: ugly) that TOML inline tables can't have new lines -- forcing single huge lines instead of readable blocks. But that's a TOML limitation apparently.

Changed, working config for reference for others that might run into similar problems:
