Why spacebar?

How to type space?
Just type spacebar.
SpaceLauncher is smart to recognize it.
What if I forget?
Hold Space and look. SpaceLauncher shows what you can press next.
Actions you use often become less prominent, so the ones you still need help with stand out.
Is this for you?
SpaceLauncher complements Spotlight-like apps such as Raycast, Alfred, and Spotlight itself. Keep search for discovery; use SpaceLauncher for actions you repeat enough to turn into key sequences.
It also owes a lot to Karabiner-style keyboard layers. Karabiner is great for low-level remapping; SpaceLauncher keeps the action layer easier to edit, with built-in actions for apps, URLs, files, scripts, menu items, and keystrokes.
If you want the spacebar as your leader key, SpaceLauncher is tuned for that: tap to type a space, hold to lead, see hints while learning, and group related actions behind prefixes.

It's uncommon,
but if you really need it, hold shift and spacebar.
From SpaceLauncher 1.2, you can type spacebar, then press and hold it quickly (by defaults in 0.2 seconds, you can set it in the option "Disable SpaceLauncher for 0.2 seconds after your last typing").
(SpaceLauncher 1.3 +)
You might notice that, in most case, you type a space quickly after finishing a word. This space shouldn't be treated as SpaceLauncher's hotkey. This option means, if you type a space in 0.2 seconds after your last keystroke, the space will be ignored by SpaceLauncher.
If the above option "Disable SpaceLauncher for 0.2 seconds after your last typing." works for you, just ignore this option.
If you often trigger SpaceLauncher actions when inputting text, that is because you type fast so that the letter after space goes before releasing spacebar. This option gives a delay. After you pressing spacebar, SpaceLauncher waits for a delay, then start to recognize keys for actions.
This is intended. The keys used recently will be gray. The keys never used or used several weeks ago will be white or less white depending on your last usage.
I also considered reordering the rows in hint window to show less used rows first. But I noticed if I referred to a row several times, I would expect it to appear in the same place. Reordering made me difficult to locate it.
Yes, you can. Holding spacebar until the hint window appears, then you drag the title bar to move the window, or drag the edge to resize width (height will be changed automatically depending on contents).
No, SpaceLauncher is a paid application.
You can try SpaceLauncher without limitation forever, but after trials, you should purchase for further use.
(SpaceLauncher 2.0 +)
After holding down the space bar for a tiny delay (0.2 sec by default), you'll see the icon. This means that you can now press a pre-defined key.
Choose Apple menu > System Settings, click Desktop & Dock in the sidebar, go to Mission Control on the right, then turn “When switching to an application, switch to a Space with open windows for the application” on.
