Tinycast ships with nothing bound. Every global shortcut is one you record.

What can have a shortcut

The palette itself (App Launcher, in Settings → General)
Every built-in command, except Open in Browser, Run Shell Command and Quit Tinycast. See Commands.
Every app, and every System Settings pane
Every quicklink, custom command, custom Quick Action and extension command
All 31 system actions
All 35 window commands, and every window layout

Each shortcut is recorded on the item's row in its Settings pane, and shows as keycaps on its launcher row.

A command that opens a screen is a toggle. Press its shortcut once to open the screen, and again to close it.

Recording one

The recorder is not a normal text field. Click it, then press the keys you want.

A small bubble above the field shows the prompt, then the modifiers you are holding, then a warning if the shortcut is already taken, naming exactly what uses it.

Recording needs no permission. Only using some kinds of shortcut does.

Double-tap modifiers

Any shortcut can instead be a double tap of one lone ⌃, ⌥, ⇧ or ⌘.

The exact rules:

A tap is a press of exactly one of those four keys, with nothing else held, no other key and no click, released within 250 ms.
A double tap is a second tap of the same key starting within 300 ms of the first release.
It fires when you let go the second time, not when you press. The key is already up when the action runs, and "double-tap and hold" does nothing on purpose.

⇧ works as a double tap, even though ⇧ alone cannot be a normal shortcut. Caps Lock cannot be used this way; that is what the Hyper key is for. Having Caps Lock on does not get in the way.

This needs Accessibility, and never asks for it on its own. The shortcut is saved anyway, the recorder shows a warning that opens System Settings, and the shortcut starts working the moment you grant access.

Tinycast only watches for double taps while at least one shortcut uses one, so if you never do, it costs nothing.

Hyper key

Settings → General → Hyper Key turns one physical key into ⌃⌥⌘, or ⌃⌥⇧⌘ with Include Shift on.

You can choose Caps Lock, Right Control, Right Shift, Right Option or Right Command.

Function keys are not offered. Their media functions fire before Tinycast can see them, so turning F1 into Hyper would still dim your screen.

Shortcuts you already use with those modifiers work with Hyper right away.

The ✦ symbol

Any shortcut that includes all the Hyper modifiers shows as a single ✦. So ⌃⌥⌘G shows as ✦G, or ✦⇧G when an extra modifier is left over.

This is simply how it is written, not a setting. With no Hyper key set, ⌃⌥⌘G shows as itself.

Include Shift

Switching this updates every saved shortcut, so nothing breaks. If an update would clash with another shortcut, that one is skipped and keeps its original keys.

The option is greyed out while Hyper Key is set to None.

Quick Press

Settings → General → Quick Press decides what pressing the Hyper key on its own does: Does Nothing (default), the key's original job, or Trigger Escape.

Escape is the favorite choice for Caps Lock users.

Caps Lock details

While Caps Lock is your Hyper key, it is remapped at the hardware level. The remap is removed when you pick another key, when Tinycast quits, and it never survives a restart.

In the brief moment before the remap takes hold, the Caps Lock light can still switch. That is the hardware, not something Tinycast can stop.

Hyper needs Accessibility and never asks for it on its own. Tinycast keeps checking, starts working as soon as access is granted, notices if access is removed, and clears a key that looks stuck. When you switch to another user, it pauses until you are back.

Hidden, switched off, and turned off

Hiding a row does not turn off its shortcut. Unticking a row's checkbox, or ⇧⌘H in the launcher, only changes what search shows.

A section's switch does turn off its shortcuts. Enable Applications, Enable System Settings, Enable System Actions and Enable Commands each stop every shortcut in their pane.

Turning a feature off turns off its shortcuts. File Search, Notes, AI, Quick Actions, Navigation, Calendar, window commands, quicklinks, custom commands and extensions all check their switch before doing anything. Turn the feature back on and your shortcuts work again.

A system action's confirmation comes up for its shortcut exactly as it does in the palette.

Keeping them

Shortcuts are included in backups, except for custom Quick Actions.

Shortcuts for things you deleted while Tinycast was not running are cleaned up the next time it starts.
