Keyboard Coordinate Entry
The Search/Replace entry in the
will popup the Search & Replace Panel.
The keyboard accelerator Meta-I will do the same.
Using the Search & Replace Panel,
users can search and optionally replace
text in the figure.
It is also possible to apply
UPDATE to searched texts.
N.B.: The Undo function
is not available for this feature.
- Specify the string to be searched. Pressing Return in this window
or pressing the Search button will start the search.
Pressing this button will start the search for the text
in the Search for entry.
The results of the search will be displayed in the bottom window, with
the coordinates of each text object containing the word or words.
- If this box is checked,
upper-case and lower-case letters will be considered significant when searching.
- Specify the string to replace the string
entered in the Search field.
- If this button is clicked after the search,
the string specified in Search for field will be replaced
with the string specified in the Replace with field.
Search must be clicked once before clicking this button.
If this button is clicked after the search,
the UPDATE function will be performed
on the matching texts, applying settings in the
to the matched text objects.
Spell Check... in the
Edit menu or
keyboard accelerator Meta-K will popup the Spell Check Panel.
Xfig will run the external spelling checker (resource Fig.spellcheckcommand)
on text in the figure,
and shows any misspelled words in the text.
N.B.: The Undo function
is not available for this feature.
- This window shows the status of the spelling checker, and how
many words (if any) are misspelled.
- This listbox shows the misspelled words, with a scrollbar if necessary
If you click on a word it is copied to the Correction window
where you may edit it to correct it. Pressing Return in this
window or the Correct button will replace all occurrances
of this word in all text objects in the figure.
- Pressing this button will do a re-check of spelling. This is useful
after correcting words to verify the corrections.
Use of a three-button mouse is recommended, but it is also
possible to use a two-button mouse (if you have a two-button mouse and
your X server doesn't emulate a three-button mouse, press the Meta (or Alt) key
and right mouse button together to simulate mouse button 2). Normally, mouse
buttons 1 to 3 are assigned to the left, middle, and right buttons respectively.
However, be warned that some window managers may use the Meta-Right button combination
to do window operations (e.g. resize). If this is the case you will have to
change the setting in the window manager.
If you use a wheel-mouse, then the following functions are available:
- Rotating the wheel on attribute buttons will increase/decrease
setting of the button as if mouse button 2 or 3 is clicked.
This can be useful to alter parameters such as Line Width.
- Rotating the wheel on a spinner will increase/decrease the value.
Rulers and Canvas
- Rotating the wheel on the rulers or canvas will scroll the canvas.
- Rotating the wheel on the canvas while the Control key is pressed
will zoom/unzoom the canvas around the pointer.
- Rotating the wheel on the canvas while the Shift key is pressed
will popup a panel to select
drawing modes (upward) and editing modes (downward).
The panel will close when any item is selected, or when the
wheel is rotated in the reverse direction.
Mouse Function Indicator shows which functions are assigned
to each mouse button.
Although the function of each mouse button changes
depending on the state (selected mode, position of the mouse cursor,
state of SHIFT key or CONTROL key, etc) at the time,
the mouse function indicator shows the current function at all times.
If the TEXT mode is selected
and it is ready to enter text from keyboard,
the mouse function indicator shows that as a keyboard icon.
If left and right mouse button are switched,
message on the mouse function indicator can be switched with
-flipvisualhints option or Fig.flipvisualhints resource.
See also Information Balloons.
If this mode is ON
(see Global Settings Panel),
`balloon' messages corresponding to the object the mouse is positioned
over will popup after a predetermined time
(in milliseconds; resource Fig.balloon_delay).
Here is an example:
In any drawing or edit mode, the location of the next point may be specified from the
keyboard rather from the pointer. Pressing Ctrl-k while the pointer is in the
canvas will pop up a dialog that allows a coordinate to be entered.
The coordinates may be specified in either rectangular or polar form, either
absolutely or realative to the current point, and in either decimal or
fractional notation. Rectangular coordinates are specified as
r x-coord, y-coord
where the comma is optional and a leading 'r' (or 'R') indicates that the point
specified is relative to the current point. Coordinates may be entered either in
decimal form or fraction form like, for example "2-7/8" and are in the
currently selected units.
Polar coordinates are entered as:
distance < angle
where the distance is always relative to the current point and, like
rectangular coordinates, may be expresed as a decimal or a fraction.
The angle may be suffixed with any of the three letters "d", "r", or
"p", in either upper or lower case. A "d" suffix indicates that the angle is in
degrees, an "r" suffix indicates radians, and a "p" suffix indicates
pi-radians. (Pi-radians are a multipler of π; ".5p" would represent the
angle π/2.) The default if no suffix is specified is degrees.
Keyboard entry is completed by pressing the Enter key. An unshifted Enter is
equivalent to a left-button pointer click at the entered location; Shift-Enter
is the equivalent of a middle-button (Button2) click and Ctrl-Enter is the
equivalent of a right-button (Button3) click.
Keyboard entry may be cancelled by pressing Escape.
The keyboard entry mechanism maintains a stack of recently entered coordinates.
While the text cursor is in the keyboard entry text field, the Ctrl-P, Ctrl-N,
Up-arrow, and Down-arrow keys navigate up and down in the stack.
