Keypad Navigation

You can quickly navigate around spectra and peak-lists using keys on the of the keyboard. To use this feature the active window must have the "focus", that is, it must be the last window you clicked the mouse in.

Alphabetic keys

Use the f,e, p, c, v, r, w, x, and y keys as follows:

f

Full View : same as Full button on icon bar (see above)

e

Expand View : same as Expand button on icon bar (see above)

p

Previous View : same as Previous button on icon bar (see above)

c

Copy View: copies current view parameters into a buffer so they can be pasted into another window. Parameters include the dataset, plot limits, contour level, borders, colors, displayed peak list etc.

v

Paste View: Sets the parameters of window to those stored in the copy buffer with copy command (see above).

r

Read Limits: Stores into a buffer the current plot limits of the window including the dataset dimensions assigned to each axis, and the chemical shift range displayed on each axis. Does not store parameters such as the assigned dataset, peak lists, colors etc. Use Copy/Paste (see above) for those parameters.

w

Write Limits: Sets the plot limit parameters of the window to those store to the limits buffer with the read limits command (see above).

x

Rotate view to show plane at position of vertical crosshair. If the current view dimensions are 1 and 2 on the x and y axes, respectively, with the vertical cursor at x=7.5ppm, this will give a display with dimensions 2 and 3 on the x and y axes, respectively, with the z axis a dimension 1 plane at z=7.5ppm.

y

Rotate view to show plane at position of horizontal crosshair. If the current view dimensions are 1 and 2 on the x and y axes, respectively, with the horizontal cursor at y=7.5ppm, this will give a display with dimensions 2 and 3 on the x and y axes, respectively, with the z axis a dimension 1 plane at z=7.5ppm.

Numeric Keypad

Use the numeric keypad to zoom and pan the spectrum as follows.

1

Pan down and to the left.

2

Pan down.

3

Pan down and to the right.

4

Pan left.

5

Shift view to center on crosshair position.

6

Pan right.

7

Pan up and to the left.

8

Pan up

9

Pan up and to the right.

-

Zoom out.

+

Zoom in.

Cursor Keys

Use the cursor keys to move up or down planes in 3D and 4D spectra, increment or decrement rows and columns in 1D displays of 2D,3D or 4D spectra, change contour levels, and rotate spectra

Down Arrow

1Dx: Move up a row. 3D,4D Spectrum: Move Down a plane.

Up Arrow

1Dx: Move down a row. 3D,4D Spectrum: Move Up a plane.

Left Arrow

1Dy: Move left a column. 4D Spectrum: Move Down a Z2 plane.

Right Arrow

1Dy: Move right a column. 4D Spectrum: Move Up a Z2 plane.

Control-Up Arrow

Increase contour level.

Control-Down Arrow

Decrease contour level.

Shift-Right Arrow

Rotates the view of the spectrum by incrementing the dimension displayed on the y axis. For example, for a three-dimensional dataset, if the dataset dimensions displayed on the x, y and z axis are 1, 2 and 3, after this key-action, the dataset dimensions will be 1,3 and 2. Clicking again will rotate the view again, back to dimensions 1,2 and 3. Rotation is around the center of the currently displayed view, so that the new chemical shift of the z axis, is the value that was at the center of the previous y axis.

Shift-Left Arrow

Same as Shift-Right Arrow, but instead the dataset dimension on the y axis is decremented. The direction of rotation only matters if the dataset has more than three dimensions.

Shift-Up Arrow

Rotates the view of the spectrum by incrementing the dimension displayed on the x axis. For example, for a three-dimensional dataset, if the dataset dimensions displayed on the x, y and z axis are 1, 2 and 3, after this key-action, the dataset dimensions will be 3,2 and 1. Clicking again will rotate the view again, back to dimensions 1,2 and 3. Rotation is around the center of the currently displayed view, so that the new chemical shift of the z axis, is the value that was at the center of the previous x axis.

Shift-Down Arrow

Same as Shift-Down Arrow, but instead the dataset dimension on the x axis is decremented. The direction of rotation only matters if the dataset has more than three dimensions.

Paging Keys

Use the Insert,Delete,Home,End,PageUp and PageDown keys to navigate peaklists.

Insert

Undelete the current peak.

Delete

Delete the current peak.

Home

Move to the first peak of current list.

End

Move to the last peak of current list.

PageUp

Move to the previous peak of current list.

PageDown

Move to the next peak of current list.
