30+
31+Clicking the symbol at the right of the search bar opens the Sigil Input Tool.
32+Use the dropdown at the top to select Galaxy, Star, or Planet.
33+Click on a square to start selecting sigil components.
34+
35+Select component catogeries on the right, and then tap the options on the sigil
36+to add them to your search.
37+
38+The ^ button goes up a level so you can select another category.
39+The X button will clear sigil components based on what type you're inputting.
40+At the top level, the X button will clear all inputs.
41+
42+Your contacts will be searched for any search.
43+When the search has become specific enough,
44+all spawned ships with matching sigils will be shown.
45+If your input is unambiguous, the page for the matching ship will be shown,
46+whether the ship is spawned or not.
47+
48+NOTE: Some sigil inputs are considered ambiguous even if they exactly match
49+a particular sigil, because further details could match a different sigil.
50+E.g. `~zod` is a circle, but a circle in the suffix position might be intended as a more general search.
51+A future version of Astrolabe will allow you to view the ship
52+whose sigil most closely matches your search, even if the search is ambiguous.
