48	48	* No tooltips (they don't show up on hover for me anyway.) Controls are
49	49	documented in this README for now.
50		* In the editing pane, pressing the tab key inserts two spaces for now.
	50	* In the editing pane, pressing the tab key rewrites the string to
	51	the left of the cursor, based on some internal rewriting rules. For
	52	example, `--` is replaced by `—`. See the source code for the full set
	53	of rules. The rewriting rules implement tabs in the following way:
	54	* four spaces are replaced by eight spaces
	55	* an empty string is replaced by four spaces
	56	* a tab character is replaced by two tab characters
	57	* `^I` rewrites to tab, so you can otherwise insert a real tab character

71	78	* Typing `{<enter>` or `:<enter>` should indent the next line four spaces.
72		* Typing `<tab>` should "tab-complete" (rewrite) the text to the left.
73		This never results in a tab character, unless a tab character is what the
74		rewrite rule says to substitute in.
75	79	* Find should support case-sensitive and maybe whole-world-only search.
76	80	* Replace found text with new text.
77		* ^F find should populate find-entry with selected text.
	81	* Ctrl+F find should populate find-entry with selected text.
78	82	* Mark and move to mark (like Ctrl+F2/F2 in SciTE)
