Modifiers
There are currently only the modifiers
- Plain
- Shift
- Control
- Shift + Control
There is no standard, which functions are to be invoked by the use of which modifiers, but there is a rough scheme, to which we should obeye when considering useful standardized shortcuts:
| Modifier | Function keys | Characters, numbers |
| Plain | Basic function | Value |
| Shift | Context / further function | Value |
| Control | Complex Function | Basic / Action shortcut |
| Plain | Complex Function | Format shortcut |
