Notations

Character-based

• :. = therefore: In PocketPC, dotting twice converts '..' to ':' so that ':.' is faster than '.:'.
• :~ = because: There is no "upper dot" in general character set. This looks close to ':.'. In Prolog programming language, ':-' is used in syntax as "(only) if" logic but that symbol in ordinary writing language rather means "such as". Tilde character in some typeface becomes upperscore.
• / done, x cancelled, . started, ^ postponed, transfered (to elsewhere), > in progress (not complete yet)

Graphical symbols

This is for use in hand-writing (among books) not text-typing (in computer).

• q

  (q) Prepare for to-do tracking: i.e., denote a task

• Triangles

  • Right-ahead: normal bullet. The 'o' symbol can confuse with text in writing. Also easier than black 'o' or square symbols.

  • Normal:

  • Upside-down

  • Left-ahead
