Chapter 7

One-Handed Input Mode

Dokusha has basic support for one-handed use. If you wish, you can operate the program just by using the 6 hardware buttons on your Palm device. This is useful if you would like to read Japanese texts on a crowded train, or if you just can't be bothered to tap the screen. Currently the following screens can be operated in one-handed mode:

The main reader screen
The dictionary screen
The kanji details screen

To enable one-handed input mode, you must go into the General Preferences page and enable the "1-Hand Input" preference. This allows you to use all the hardware buttons on your Palm device to control Dokusha, but prevents you from switching applications using the buttons (you can still switch applications using the silkscreened Applications or Calc buttons).

In this chapter, the hardware buttons are named as follows:

Button 1: The leftmost button (Date Book on most devices).
Button 2: The second button from the left (Address Book).
Button 3: The third button from the left (To Do).
Button 4: The rightmost button (Memo Pad).

The main reader screen

The hardware buttons have the following effect in the main reader screen:

Button 1: Successive presses move the selection down the screen one line at a time.
Button 2: Successive presses move the selection to the right one column at a time. Can only be used after the correct row is selected using Button 1.
Button 3: Extends the selection by one character.
Button 4: Searches on the current selection. Has the same effect as tapping the Find button at the bottom of the screen. Note that you can change the function that is executed in the Preferences.

The dictionary screen

The hardware buttons have the following effect in the dictionary screen once you have looked up a word:

Button 1: Successive presses select successive Kanji characters in the dictionary entry at the top of the screen.
Button 2: Same as Button 1.
Button 3: Cancels the dictionary lookup and returns to the previous screen.
Button 4: Looks up details for the selected Kanji character.

The kanji details screen

The hardware buttons have the following effect in the kanji details screen:

Button 1: Same as pressing the Find First button.
Button 2: Same as pressing the Find Any button.
Button 3: Cancels the Kanji Details screen and returns to the previous screen.
Button 4: Same as Button 1.
