"Let's model me a mine"
M.E.G.M.S.
Mining & Exploration Geological Modelling Services
The MEGS_Log window has two scrollbars, one on the far right of the window, to control the vertical position of the right borehole and trace fields, and the other scrollbar located between the left and right borehole fields, to control the vertical position of the left borehole field.
When the Link Scrollbars setting is on then scrolling of the right hand scrollbar also moves the left hand scrollbar. The linking is only one way - movement of the left scrollbar does not move the right hand scrollbar.
In addition to using the mouse to manipulate the scrollbars, you can scroll the display by using the Ctrl-Up and Ctrl-Down shortcut keys. These keys move the scrollbar that contains the currently select field and also honour the Link Scrollbars setting, ie. if the right hand borehole field or a trace field is selected and Link Scrollbars is on, then the Ctrl-Up and Ctrl-Down shortcut keys also scroll the left hand borehole field.
You can also set the absolute position of the the top of the display by using the Set Display Top Depth dialog box.
