# Your first shortcut (/get-started/first-shortcut)
Open Lumi from the menu bar and pick the **Shortcuts** pane. It is what settings
opens on.
## Add a row [#add-a-row]
1. Press **Add shortcut**.
2. Click the trigger field and *press the combination you want*. The field
records what you press rather than asking you to spell it out.
3. Pick an action.
4. Fill in whatever that action asks for.
5. Press **Save**.
That is the whole loop. The row is live the moment it is saved — there is no
apply step and no restart.
## Try this one [#try-this-one]
A good first shortcut is **Toggle application**, because it is the one that has
no equivalent anywhere else in macOS: the same combination shows the app and
hides it again.
| Field | Value |
| ----------- | -------------------------------------------------------------- |
| Trigger | ⌥Space, or whatever is free |
| Action | Toggle application |
| Application | Your terminal, notes app, or anything you reach for constantly |
Press it once and the app comes forward. Press it again and it goes away.
## Three rules worth knowing early [#three-rules-worth-knowing-early]
### Save is when a form is checked [#save-is-when-a-form-is-checked]
The Save button is always enabled. Press it with something missing and the
error appears under the field that is wrong, and focus moves there. Nothing is
said about a field you have not filled in yet.
The exception is anything about the gesture you just made — a combination
already taken by another row, or one macOS will not let anybody register. Those
are said immediately, because they are facts about the key you just pressed
rather than about a form you are still writing.
### A row that fails says so twice [#a-row-that-fails-says-so-twice]
A press that cannot be carried out — no Accessibility grant, an application that
has been moved, a flow that is switched off — puts an alert on screen for two
seconds *and* pins the reason to the row in the Shortcuts pane. The alert is
because the normal state of Lumi is no window open; the row is because the
alert is gone in two seconds.
### Disabled is not deleted [#disabled-is-not-deleted]
Every row has a switch. A row that is off claims nothing — the combination is
free for something else to take — and turning it back on re-registers it. There
is no difference between a disabled row and a deleted one as far as the
keyboard is concerned, which is what makes the switch a safe thing to try.
## Where to go next [#where-to-go-next]
Everything a combination can be bound to.
When you run out of combinations worth remembering.
Turning Caps Lock into a modifier nothing else uses.
