Insert Table command, Suggestions for keyboard combo

Here are some options that keep things mnemonic and avoid conflicts with what you already use:

You already have:

Ctrl+T → Insert Table
Ctrl+Shift+T → Insert Table of Contents

Option A: Keep all table-structure ops on the T key

Core idea:

T alone: create
Shift+T: “bigger” construct (Table of Contents)
Alt+T variants: structural edits on tables

Suggested mappings:

Merge with Table Above → Ctrl+Alt+Shift+T
Merge with Table Below → Ctrl+Alt+T
Split Table → Ctrl+Alt+S (S = Split)

Pros:

Easy grouping in your head: “table operations = Ctrl + Alt (+ maybe Shift) + T”
Above vs below mapped to adding Shift (above often associated with “up”/“more”)

Cons:

Ctrl+Alt+Shift+T is a bit of a finger stretch.

Option B: Use arrow keys to reflect direction

Merge with Table Above and Below naturally lend themselves to ↑ and ↓.

Merge with Table Above → Ctrl+Alt+Up
Merge with Table Below → Ctrl+Alt+Down
Split Table → Ctrl+Alt+S or Ctrl+Alt+\\

Pros:

Extremely intuitive; you’ll remember instantly which way the merge goes.
Doesn’t conflict with Ctrl+T or Ctrl+Shift+T.

Cons:

Might overlap with existing OS/editor shortcuts, depending on your environment.

Option C: Column/row editing style (if you want everything on T)

If you really want all table operations on T and don’t like arrows:

Merge with Table Above → Ctrl+Shift+Alt+Up (directional & explicit)
Merge with Table Below → Ctrl+Shift+Alt+Down
Split Table → Ctrl+Shift+Alt+T

This keeps all three tightly grouped but is more complex to press.

My strongest practical recommendation

If your environment doesn’t heavily use Ctrl+Alt+Arrow:

Merge with Table Above → Ctrl+Alt+Up
Merge with Table Below → Ctrl+Alt+Down
Split Table → Ctrl+Alt+S

It’s fast, directional, and easy to remember, while keeping Ctrl+T / Ctrl+Shift+T clean for insertion commands.

If you tell me what OS/editor or keybindings you’re already using (VS Code-style, Emacs-style, etc.), I can fine-tune these to avoid collisions.
