No. ctl+left does what you said Home did. If you want Home to go to the left, then you will have to code this.
private void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
this.lastKeyDown = e.KeyCode;
if(e.KeyCode == Keys.Home && Control.ModifierKeys == Keys.None)
{
GridCurrentCell cc = this.gridControl1.CurrentCell;
cc.MoveTo(cc.RowIndex, this.gridControl1.Model.Rows.HeaderCount + 1);
}
}
