Problem Adding Keyboard Shortcut

I created a custom keyboard shortcut, Ctrl A, for the Run > Run All Cells menu item. It works, but it doesn’t show up in the Run menu. How can I make it show up? Here’s the beginning of my shortcuts.jupyterlab-settings file (macOS Sequoia 15.5):

{
“shortcuts”: [
{
“command”: “notebook:run-all-cells”,
“keys”: [
“Ctrl A”
],
“MacKeys”: [
“Ctrl A”
],
“selector”: “.jp-Notebook:focus”,
“args”: {},
},
{
“command”: “notebook:run-all-cells”,
“keys”: [
“Ctrl A”
],
“MacKeys”: [
“Ctrl A”
],
“selector”: “.jp-Notebook.jp-mod-editMode”,
“args”: {},
},
{
“command”: “runmenu:run-all-cells”,
“keys”: [
“Ctrl A”
],
“MacKeys”: [
“Ctrl A”
],
“selector”: “[data-jp-code-runner]”
},
[snip…]
]
}

I think that last sentence from another thread is about your question of:

My understanding is that isn’t how things work at this time. You know it is a shortcut and can see it in the shortcut settings where you customized things when you look there.
You’d have to add your suggestion for improvement there in that issue.
