How to type "Full Width" characters? I would like to be able to type with the "full width" characters, such as

ａｂｃｄｅｆｇｈｉｊｋｌｍｎｏｐｑｒｓｔｕｖｗｘｙｚ

and

ＡＢＣＤＥＦＧＨＩＪＫＬＭＮＯＰＱＲＳＴＵＶＷＸＹＺ

or

０１２３４５６７８９

or even 

！＃＄＆＊＋－＜＝＞？＠［＼］＾＿｛｜｝～｟｠￠￡￢￣￤￥￦

without having to resort to "hunting and pecking" via the Symbols and Emoji dialog..



Is this possible without laboriously assigning macros for each character via OS X's "shortcuts" (or BetterTouchTool, etc)?
• Open system preferences

• Select ‘Keyboard’

• Go to the ‘Input sources’ tab

• Click on the plus button at the bottom to add a keyboard format

• Select a keyboard format that supports full-width text (e.g. Japanese)

• Make sure that the full-width input mode is enabled. (For the Japanese keyboard menu you will need to tick the box next to ‘Full-width Romaji’)

• Make sure that the ‘Show Input menu in menu bar’ box is ticked

• Select the full-width mode in the menu bar

• You should then be able to type in full-width text
