- Most of DAN's operating parameters can be set via a form. Within a
- form the following keys are usually available:
-
- TO SELECT A FIELD
- -----------------
- cursor Up,Down Move up or down one field. Both keys wrap around
- to the first or last fields. Active field will be
- highlighted.
- Ctrl-cursor Right Move to field to the right of the current field.
- Ctrl-cursor Left Move to field to the left of the current field.
- Ctrl-Home Move to first field on current form.
- Ctrl-End Move to last field on current form.
-
- MOVEMENT WITHIN A FIELD
- -----------------------
- cursor Right,Left Move one character to the right or left.
- Home Move to first character of field
- End Move to character at end of field
- +
- MODIFYING FIELD VALUES
- ----------------------
- Normally, you type in a new value and hit `Enter' to indicate you
- are done modifying the field value. However, you can also use the
- following keys:
- Ins Toggles between insert and overtype mode. Insert
- mode is indicated by a highlighted `insert' in the
- upper right corner of the screen. Insert mode causes
- characters to be inserted in the field to the left of
- the current cursor position. Overtype mode causes
- typed characters to replace the character under the
- cursor.
- Del Deletes the character under the cursor.
- BkSp Deletes the character to the left of the cursor.
- F5 Resets the current field to 0 for numeric fields
- or blanks for text fields.
- F7, F8 Decrement (F7) or increment (F8) the field value by
- 1 for numeric fields, or move backward or forward
- through the possible choices for a CHOICE field.
- +
- MODIFYING FIELD VALUES
- ----------------------
- F9 Toggle YES/NO fields. That is, convert a YES value
- to NO and convert a NO value to YES. YES/NO fields
- are indicated by a `?' character in the field label.
- F10 Display possible choices for a CHOICE field. Use
- the cursor keys to highlight the desired choice and
- hit either `F10' or `Enter' to select that choice.
- Alternatively, type several leading characters from
- the name (enough to uniquely identify the choice), and
- then hit `Enter'. Usually, just the first character
- of the choice name is sufficient to select that value.
- +
- TERMINATING FIELD MODIFICATIONS
- -------------------------------
- Enter Truncates all characters to the right of the cursor
- position and enters the new value.
- cursor Up, Down Leaves characters to the right of the cursor position
- alone and moves to the next field up or down from
- the current field. Use this method when you want to
- keep most of the existing field characters; for
- example, when only the second character in a 20
- character field needs to be changed.
- F4 Acts like `Enter' but causes some function to be
- executed. For instance, on the File form this
- key indicates that all fields on the form are set up
- and the specified algorithm is to be loaded. In other
- cases (e.g. Plot Controls form) the algorithm is
- executed. See the function key definitions at the
- bottom of the form.
- Esc Cancels modifications to the current field and
- restores the previous, unmodified value.
- +
- EXIT THE FORM
- -------------
- Esc If the current field has not been modified then the
- Escape key closes the form.
-
- MISCELLANEOUS
- -------------
- F1 Display help information for the highlighted field.
- Shift-F2 Allows direct access to another form without having
- to exit the current form (this key also works in
- the Editor). Use `F10' to see your choices, or type
- the first few letters of the form name.
