Two-step hot-keys
The two-step hot-keys require that press different keys twice to finish a hot-key operation. For example of the End -> Up, it is necessary to press End key once, then press the Up key. When the End key is pressed, ReoGrid will enter Two-step hot-keys process mode to wait the second hot-key; If any unexpected key is pressed or other operations is performed, the hot-key operation will be aborted.
- End -> Up – Move selection to first row at current column (Same as Ctrl+Up)
- End -> Down – Move selection to last row at current column (Same as Ctrl+Down)
- End -> Left – Move selection to first cell at current row (Same as Ctrl+Left)
- End -> Right – Move selection to last cell at current row (Same as Ctrl+Right)
- End -> Shift + Up – Move selection to first row to expend current selection (Same as Shift+Ctrl+Up)
- End -> Shift + Down – Move selection to last row to expend current selection (Same as Shift+Ctrl+Down)
- End -> Shift + Left – Move selection to first column to expend current selection (Same as Shift+Ctrl+Left)
- End -> Shift + Right – Move selection to last column to expend current selection (Same as Shift+Ctrl+Right)
Key process events
ReoGrid provides the two events that is used to handle keyboard operations:
- BeforeCellKeyDown
- AfterCellKeyDown
It is possible to disable the hot-key by handling BeforeCellKeyDown, which has the event argument where could set IsCancelled property or change the key-data. The key process flow is ‘Before -> hot-keys -> After’. See also Handling keyboard events.
Behavior affected by settings
Some behaviors may be affected by the workbook and worksheet settings. For example, when a cell was set as read-only by programming, the F2 and F4 might become no longer available. See behavior and settings.
