Speed Keys Supported
The OpenROAD keyboard map file is a text file with a specific format. The file describes 23 OpenROAD system-defined keys, and 36 user-defined keys. The file contains one line for each key with four entries for each line. The entries are arranged in four columns separated by tabs. All of the columns are mandatory.
Because the contents of some columns require specific values, it is best to copy one of the existing keyboard map files and use this file as a template if you want to modify the file or create a new one.
The following table describes the columns:
Column
Description
1
Index that OpenROAD uses to map the key. It is read into memory and must always match the text label in column 4.
Do not change the entries in this column.
2
Text that appears in the pull-down menu for the speed key.
3
Virtual key name for keystroke that occurs.
4
Internal symbol name used by OpenROAD, which must match the index in column 1.
Do not change the entries in this column.
The following virtual key definitions can be used to define key strokes:
VK_BACK      VK_TAB        VK_RETURN      VK_SHIFT      VK_CONTROL
VK_MENU      VK_PAUSE      VK_CAPITAL     VK_ESCAPE     VK_SPACE

If a key is defined in the mapping file, it will activate if assigned to an actual menu item. For example, if the VK_RETURN key is mapped to SK_USER1 and SK_USER1 is not used, then it will not change any behavior. On the other hand, if it is assigned to a menu item attached to the frame, then it will override the default behavior and raise that event block.
The same mapping is now used for all platforms. The older definitions in the PC keyboard files still work. Any keyboard file that used UNIX definitions will need to be changed to use the new virtual key definitions.
Now 104 different key definitions are available. OpenROAD still has a limit of 59 slots available for speed key definitions which are active for the life of a session.
