Simplified Cangjie is one of the few input methods which has an IME pre-installed on Traditional Chinese-capable personal computers.
The user must choose from a list of candidate characters, which can be compared to "hunt and peck" vs. ordinary touch typing.
Microsoft Quick IME is bundled with all Traditional Chinese editions of Windows 3.1x or higher.
The Cangjie IME itself has evidence of a strong presence in Hong Kong with it being available on most operating systems and keyboard layouts.
Indeed, children in Hong Kong learn Chinese characters from the very beginning in kindergartens; in contrast, in mainland China and Taiwan, transliteration systems like pinyin or zhuyin are taught first before introducing any Chinese characters to children.
