v2.8

Changes in this release:

• Fixed bug in Average Error Rate display.
• Fixed button width collapse when labels and thumbboard are disabled.

v2.7

This release adds the option View | Show letters only. When selected, the keymap shows only the alphabet plus SP, BS, DEL, and NL.

This option is enabled by default, to reduce the cognitive load for learners.

Issues:
Average Error Rate incorrectly shows 100% regardless of input.
This will get fixed in the next release.

v2.6

Changes in this release:

• use bullets to denote anchor buttons in chords, per popular convention.

v2.5

Changes in this release:

Persist all user preferences including the user's selected keymap, current lesson number, and all View menu options.

v2.4

This release further simplifies the visual layout of 2-button chords.
It uses the current popular convention of showing a 4x3 grid with an anchor button in the top row.

The README.md has been updated to describe the visual chord layout.

Changes in this release:

• View | Show chords: show the anchor key in the top row of each 2-button chord grid.
• use Java properties file to hold the version number

v2.3

In the process of trying to clarify how chords are illustrated, and the 2-button visual keymap, it became clear that the Default keymap will be easier to document. Thus this release makes the Default keymap the default for Twidor.

I personally like Backspice, and users can load it via the "Keymap" menu. But there are certain examples that are much simpler with the Default map.

Changes in this release:

• The factory default keymap is the default in Twidor.

The number of colors is reduced, to simplify

• Key labels are black (not colored). Green/Blue/Red is applied to button borders only.
• Correct/incorrect entered text is in grey/black, respectively.
• Highlighted lesson text and corresponding button background is red.

The 2-button visual layout is simplified:

• redundant mappings (in rows 3 and 4) are removed.
• MCCs are shown only when "show multiple character chords" is enabled.
• together, these greatly reduce the visual clutter.

v2.2

This release simplifies the menu options for enabling/disabling hinting of multiple character chords. The documentation was so confusing, the options may not have been useful at all.

Multiple Character Chords (MCCs)

Some chords send more than one letter, such as "is", "in" and "it" in the key-map above. These are called a multiple character chords (MCCs).

Twidor can optionally show hints for multiple character chords if you enable it. However, by default Twidor shows green highlights only for chords that send a single character, as shown for the highlighted letter "d", above. This is intended to make learning easier initially.

If you wish to learn all available chords, un-check the box View | Hint single letters only. This will show green highlighted buttons for the longest matching multiple character chord. For example, given the text, "the", Twidor will highlight the chord that sends "the", rather than "th" or "t".

Note that this affects only the green highlighted "hints". The Twiddler itself is capable of sending MCCs, and Twidor will accept MCCs as input, and score input text correspondingly regardless.

v2.1

Changes in this release:

• Simplified the default startup configuration: single letter chords only, and a reduced keymap.
• Simplified menu option descriptions.
• Use green for highlighting both the next letter of the lesson and the buttons that send it, for better visual intuition.
• Added version number to "About" dialog.

v2.0

Changes in this release:

• Menu option to show/hide 2-key chords in visual keymap
• fix highlighting after show/hide features are toggled.

v1.9

Changes in this release:

• Improve display of macros and special keys (eg ESC)
• Support capital (uppercase) letters.
• Fix unicode special characters.
• Allow comments in CSV keymap files.
