- Function Key Handler
- ====================
-
- This disk contains a function key handler which allows the function keys to
- be defined and activated within the RISC OS environment.
-
- The contents of this disc, are as follows;
-
- !ReadMe This file.
- !Boot Keys !Boot file.
- !Run Keys !Run file.
- !RunImage Keys code.
- !RunMe Display !ReadMe file.
- !Help Help text file
- !Sprites Directory of sprite files for the Keys application.
- Templates Window templates.
- StdKeyDef Default Key definitions called up by !Run file.
- Modules Module directory containing :
- Clib The Shared C Library module from the RISC OS !System folder.
-
- Memory Requirements
- ===================
-
- Module Area Sufficient for Clib
- Program Area 96K
-
- Getting Started
- ===============
-
- To copy this application onto another disc or install it on the hard disc
- open a directory viewer on the destination disc within the RISC OS Desktop
- and drag the !Keys icon to the destination directory.
-
- The function key handler may be installed on the iconbar by double clicking
- on the !Keys application icon.
-
- The function keys are then active.
-
- The function keys may then be displayed just above the icon bar by selection
- of the Keys icon on the iconbar.
-
- The keys application is controlled by the keys menu accessed by pressing the
- menu button while the mouse pointer is over the Keys iconbar icon.
-
- The function of the menu options is as follows:
-
- Info provides current information about the application.
-
- Define opens a dialogue window allowing the operation of any of the
- function keys F1 to F12 to be defined.
-
- Show controls the display of the function keys just above the iconbar.
- This allows the function key to be operated by selecting the displayed
- key as well as pressing the keyboard key. A tick indicates the state of
- the function keys display.
-
- Save allows the current key definitions to be saved to a file using the
- standard 'Save as:' convention used by RISC OS applications.
-
- *Command opens a dialogue window allowing the entry of a * command.
-
- Quit removes the !Keys application from the Task memory.
-
- Detailed Operation
- ==================
-
- If a function key has been defined then it will always be operated on
- selection of the displayed key.
-
- If a window has the input focus then keyboard functions keys may be handled
- directly by the corresponding application, e.g. Edit. Function keys not
- recognised by the application should be passed on and subsequently processed
- by the function key handler.
-
- If a function key is not defined the key code will be passed on to the wimp.
- In this case the function key may have a name, e.g. selecting F12, which has
- the name *, will allow the input of *commands below the iconbar.
-
- Key Definition Files
- ====================
-
- The definition of the function keys may be specified by creating a KeyDefs
- file, this has the following format.
-
- Each key definition appears on a separate line.
-
- The definition is introduced by the command 'key'
-
- The function key number appears in columns 5 and 6.
-
- The name assigned to the function key appears in columns 8 to 12 and may
- be no more than 5 characters long. This name appears on the function key
- displayed above the iconbar.
-
- The operation assigned to the function key is a string on no more than 75
- characters starting in column 14.
-
- An example of this format can be seen in StdKeyDefs.
-
- The definition of the function keys may also be specified by using the
- Define menu option and the saved to a KeyDefs file by using the Save menu
- option. This automatically produces the correct format for the KeyDefs file.
-
- File Types
- ==========
-
- As distibuted the !Boot file defines the file type for KeyDefs as 701 and
- sets up a run type alias for this file type.
-
- The file type for KeyDefs may be set to any legal type the user requires.
- However a file type for KeyDefs must be set for correct operation of the
- !Keys application.
-
- Limitations
- ===========
-
- Only the Function Keys F1 to F12 can be defined.
-
- Function Keys modified by the Control or Shift keys are not handled.
-
- Operation with a multisync monitor has not been checked.
-
-
- *Command Entry
- ==============
-
- *Commands may be entered using the *command dialogue box. If no window has
- the input focus, i.e. contains the caret, then the *command dialogue box
- will be displayed on entry of the first character of the required command.
- Otherwise the dialogue box can be opened using the *command entry in
- the Keys icon menu.
-
- The dialogue box will accept a command string of up to 255 characters.
-
- The dialogue box provides full editing features for the entered string, as
- follows:
-
- Delete delete character to the left of caret.
- Copy delete character to the left of caret.
- <- move caret left one character.
- -> move caret right one character.
- Shift Copy delete word (forwards).
- Shift <- move left one word.
- Shift -> move right one word.
- Ctrl Copy delete to end of line (forwards).
- Ctrl <- move to left end of line.
- Ctrl -> move to right end of line.
-
- The entered command can be aborted by selecting the CANCEL icon.
-
- The *command is actioned by selecting the OK icon or pressing the <CR> key.
- Any output text is displayed within a mode 4 window.
