“Magic sequences” a la Markdown

Some character sequences, when typed inside the note editor, cause formatting to be applied to the text:

If following characters typed in first position of a paragraph then it gets transformed into:

`#_` or `1._`	ordered list item
`*_`	unordered list item
`-_`	definition list item
`^_`	checkmark list (a.k.a. todo)
`>_`	quote block
`_	“backtick” + space, preformatted text block
`h1_` .. `h6_`	headers of level 1,2,3,4,5 and 6
`[c:r]_`	creates table of `c` number of columns and `r` number of rows. `c` and `r` are single digits here.
`[c:r:ch:rh]_`	creates table of `c` number of columns, `r` number of rows, `ch` number of header columns and `rh` number of header rows. `c,` `r`, `ch` and `cr` are single digits here. Example: typing [3:3:1:1] will create 3*3 table with single header row and column.

where _ is space symbol.
