<h1>EDITOR COMMANDS</h1><br>
|
||
|
|
<p>
|
||
|
|
Most editing commands are available in the menu, but definitely key-bindings and Mouse actions
|
||
|
|
are the most effective way to build and arrange schematics, so you should learn at least the
|
||
|
|
most important ones.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
The basic principle in XSCHEM is that first you select something in the circuit then you
|
||
|
|
decide what to do with the selection.
|
||
|
|
For example, if you need to change an object property you first select it (mouse click) and then
|
||
|
|
you press the edit property (<kbd>'q'</kbd>) key.
|
||
|
|
It you need to move together multiple objects you select them (by area or using multiple mouse
|
||
|
|
clicks with the <kbd>Shift</kbd> key), then you press the move (<kbd>'m'</kbd>) key.
|
||
|
|

<h3>KEYBIND CUSTOMIZATION</h3>
|
||
|
|
<p>
|
||
|
|
changes to default keybindings may be placed in the <kbd>~/.xschem</kbd> file as in the following examples:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
## replace Ctrl-d with Escape (so you won't kill the program :-))
|
||
|
|
set replace_key(Control-d) Escape
|
||
|
|
## swap w and W keybinds; Always specify Shift for capital letters
|
||
|
|
set replace_key(Shift-W) w
|
||
|
|
set replace_key(w) Shift-W
|
||
|
|
</pre><br>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>STRETCH OPERATIONS</h3>
|
||
|
|
<p>
|
||
|
|
An important operation that deserves a special paragraph is the <kbd>Stretch</kbd> operation.
|
||
|
|
There is frequently the need to move part of the circuit without breaking connections, for
|
||
|
|
example to create more room for other circuitry or just to make it look better.
|
||
|
|
The first thing to do is to drag a selection rectangle with the mouse holding down the
|
||
|
|
<kbd>Ctrl</kbd> key, cutting wires we need to stretch:
|
||
|
|
</p>
|
||
|
|
<img src="commands1.png">
|
||
|
|
<p>
|
||
|
|
After selection is done hit the move (<kbd>'m'</kbd>) key. You will be able to move the selected part
|
||
|
|
of the schematic keeping connected the wires crossing the selection rectangle:
|
||
|
|
</p>
|
||
|
|
<img src="commands2.png">
|
||
|
|
<p>
|
||
|
|
In our example we needed to move up part of the circuit, the end result is shown in next picture.
|
||
|
|
Multiple stretch rectangles can be set using the <kbd>Shift</kbd> key in addition to the
|
||
|
|
<kbd>Ctrl</kbd> key after setting the first stretch area.
|
||
|
|
</p>
|
||
|
|
<img src="commands3.png">
|
||
|
|
|
||
|
|
<h3>PLACE WIRES SNAPPING TO CLOSEST PIN OT NET ENDPOINT</h3>
|
||
|
|
<p>
|
||
|
|
The (uppercase) <kbd>'W'</kbd> bindkey allows to place a wire putting start (and end point, later) to the
|
||
|
|
closest pin or wire endpoint, this will make it easier to connect precisely without the need to zoom in all times.
|
||
|
|
</p><br>
|
||
|
|
<h3>CONSTRAINED MOVE</h3>
|
||
|
|
<p>
|
||
|
|
while creating wires, lines, and moving, stretching, copying objects, pressing the <kbd>'h'</kbd> or <kbd>'v'</kbd> keys
|
||
|
|
will constrain the movement to a horizontal or vertical direction, respectively.
|
||
|
|
