Also, the user can move directly to any unknown kanji and access any of its information. This may be the Wordtank's most useful feature. Similar to this feature is the ability to store the last several words in a 'history' file, to be returned to at any time. The calculator and memo fields are not particularly noteworthy, though the built in currency and tax conversion functions may be useful to international travelers. The ability to use the memo files as kanji flashcards, however, could be useful to students of Japanese.
Users can save kanji characters to memo fields, then display only the pronunciation of the kanji.
The user can then press the 'change' button to display the character's complete information for reference. Probably the first characters that many new Wordtank users will look up are those appearing on the device's keypad, as all button labels are in Japanese. The English documentation included with the Wordtank explains the functions of each key, but until the labels become familiar, many users may have to keep the manual handy. Though not very intuitive, the on-screen interface does become easier to understand with practice. Sometimes the user must use trial and error to distinguish which of the two sets of arrow keys control each function.
