I wrote previously about how こめ can be switched to ※ with Japanese input systems. Well, I’ve discovered through a friend at work that there are a number of other tricks you can do with 変換.
Arrows – Type in やじるし and you can get these: →, ←, ↑, ↓.
Circles – Type in まる and you can make these: ○, ●, ◎, ◯, ◉. (The third is called a にじゅうまる, maybe the fifth as well.)
Triangles – Type in さんかく and you can get: △, ▲, ▽, ▼.
Squares – Type in しかく and you can get: □, ■, ◇, ◆.
Anyone know of any others? I’m using Kotoeri, the default Japanese input for OSX. Apparently it has some bugs. "kernel panic" is going to be my new catch phrase when shit goes wrong.
