Chapter 15. Keyboard and mouse shortcuts

Scream has lots of keyboard and mouse shortcuts which can be used to make routine tasks faster and easier. The most useful ones are listed in the sections below.

15.1 The Main Window

15.1.1 Menu items

A number of menu options from the Main Window have equivalent keyboard shortcuts:

+

Select all streams

+

Open the ViewInfo window

+

Open the Network Control window

+

Open the Setup window

+

Open the Summary window

+

Open a new, empty WaveView window

15.1.2 The source tree

When an entry in the left-hand pane (the source tree) is selected, you can navigate with the arrow keys:

Move to the previous entry

Move to the next entry

or

“Roll up” the current entry

or

“Unroll” the current entry

Other shortcuts in the source tree include:

+

or

+

Expand all "rolled up" sub-trees

+

or

+

"Roll up" all sub-trees

Remove the currently selected entry (if not  Files or  Network) and any sub-entries. This action also clears from the stream buffer any data associated with the deleted streams.

Note: Deleting an active source when recording is enabled has the side-effect of flushing any buffered data to disk. The source will reappear as soon as the next packet is received.

Variable - see below:

: The function of the Enter key changes, depending on the type of item that is selected in the source tree:

the Files section header

equivalent to picking Replay files… from the File menu (see section 11.2 on page 140)

a file

no action

the Network section header

open the Network Control window (see section 4.3 on page 19)

a host

directs a web browser to open the address of the PC, NAM or EAM.

a serial port

open a terminal session to an attached digitiser (see section 8.1 on page 85)

a digitiser

opens the Control window (see chapter 10 on page 112)

: If the stream list has too many entries to fit into the pane, the pane contents can be scrolled using the mouse wheel.

15.1.3 The stream list

If the right-hand pane (the streams list) is selected, the keys perform the following actions:

Move to the previous stream.

Move to the next stream.

+

Extend the selection to the previous stream

+

Extend the selection to the next stream

Open a new WaveView window on the currently-selected streams.

Remove the currently-selected streams, and clear their data from the stream buffer.

Note: Deleting an active stream when recording is enabled has the side-effect of flushing any buffered data to disk. The stream will reappear as soon as the next packet is received.

: If the source tree has too many entries to fit into the pane, the pane contents can be scrolled using the mouse wheel.

15.2 WaveView windows

Most of the functions of WaveView windows can be accessed by a keystroke, a mouse movement or the combination of the two. This is particularly useful if you have removed the window decoration with the No Caption menu option.

15.2.1 Shortcuts for all streams

or

Increase the amplitude scale (zoom in vertically)

or

Decrease the amplitude scale (zoom out vertically)

“Roll up” the current entry

“Unroll” the current entry

or +

Increase the time scale (zoom in horizontally)

or +

Decrease the time scale (zoom out horizontally)

+

Set all scales to unity (i.e. display all amplitudes in counts)

Enter or leave "pause" mode (stop or start scrolling)

+

Scroll forwards in time when in pause mode

+

Scroll backwards in time when in pause mode

+

Create a duplicate window as an exact copy of the current WaveView window, with all settings the same

Toggle the filter on or off

+

Open the Filter Design window - see section 6.3

+

Null the offsets of all unlocked streams in the WaveView window, so that the mean value of each is centred vertically in its respective lane

+

Toggle the spectrogram of all streams on or off

+

Increase the colour brightness of all spectrograms

+

Decrease the colour brightness of all spectrograms

Toggle the display of "lane lines" on or off

Toggle “overlay mode” on or off. In “overlay mode” all streams are drawn in the centre of the window, rather than having separate lanes. See also the following two entries

Restore standard axis spacing (see section 6.1.8). If standard spacing is already in force, this will recompute the display cache and redraw the contents of the WaveView window, cancelling any selection

the F6 key

Overlay streams

the F7 key

Space stream axes according to the instrument's depth. The calvals must contain a depth= entry for every stream in the window

the F8 key

If calvals contains position entries for every stream in the current window, this key will space the stream axes according to the distance from a set point, specified using…

+the F8 key

Specify a set point for axes spacing

Toggle “no caption” on or off

+

Remove all streams from the WaveView window

+

Sets the offsets all streams to zero. This may make some or all traces move vertically outside of their lanes or even outside of the WaveView window.

15.2.2 Shortcuts for the selected stream

There are also shortcuts which affect only the stream containing the mouse pointer. These are equivalent to the stream actions on the context-sensitive menu.

Remove the active stream from the WaveView window

Display the Colour selection dialogue box for the active stream

Toggles on or off the Details window for the active stream

Null the offset of the active stream in the WaveView window, so that the mean value is centred vertically in its lane

Scale the active stream

+

Scale all other streams to have the same (visual) peak-to-peak amplitude as the active stream

Sets the scale to unity (i.e. display the amplitude in counts)

Sets the offset of the current stream to zero. This may make the trace move vertically outside of its lane or even outside of the WaveView window

Toggle on or off the spectrogram display for the active stream

Increase the colour brightness of the active stream's spectrogram

Decrease the colour brightness of the active stream's spectrogram

15.3 Details window

The following shortcuts are active when the Details window has focus.

Increase the stream's offset by one pixel (regardless of any scaling on the stream)

Decrease the stream's offset by one pixel

Increase the stream's offset by the width of one lane

Decrease the stream's offset by the width of one lane

Null the offset of the associated stream, so that the mean value is centred vertically in its lane
