Text Entry
The text entry screen (title: Text entry) is used whenever an app needs free-text input — for example entering a callsign, filename, or label. It is opened automatically by apps that require it; it cannot be accessed directly from the menu.
Layout
The keyboard is a 5-column grid of 29 character buttons. Below the grid are four action controls:
| Control | Function |
|---|---|
| Shift (icon) | Cycle shift state: off → on (once) → locked → off |
<DEL |
Delete the last character |
Mode button (e.g. 123) |
Switch to the next character set |
OK |
Confirm entry and return to the calling app |
Above the grid, the current text is shown with a cursor. Below the grid are two helper fields:
- Raw: — a number field (1–255). Selecting it inserts the character with that ASCII code directly.
- AKA: — shows the character corresponding to the current Raw value.
Character sets
The keyboard cycles through three sets using the Mode button. The button always shows the next set's name:
abc — Letters
- Normal:
a b c d e f g h i j k l m n o p q r s t u v w x y z , . - Shifted (once or locked): same in uppercase
A B C … Z , .
123 — Digits and punctuation
- Normal:
1 2 3 4 5 6 7 8 9 0 ( ) ' ` " + - * / = < > _ \ ! ? , . - Shifted (locked only):
! @ # $ % ^ & * ( ) [ ] ' ` " { } | : ; < > - _ ~ ? , .
Note
In
123mode, the Shift button skips the one-time shift state and goes directly to ShiftLock. Single-character capitalisation is only available inabcmode.
hex — Hexadecimal
1 2 3 4 5 6 7 8 9 0 A B C D E F(space)- Shift has no effect in this mode.
Shift states
The Shift button cycles through three states:
| State | Shift button colour | Effect |
|---|---|---|
| Off | Dark (default) | Normal characters |
| On (once) | Darker | Next character typed is uppercase/shifted; then resets to off automatically |
| Locked | Blue | All characters are uppercase/shifted until unlocked |
Navigation
- Encoder dial: moves the highlight through all 29 character buttons in order.
- Touchscreen: tap any button directly.
- Hardware buttons (D-pad): navigate between buttons.
The cursor position in the text preview can be set by tapping a position in the text field if supported by the calling app.
