To control console and graphics visibility

Olex2 has a built in console for typing commands. Sometimes it is desirable to see only the text (output) or the structure. There are several commands and shortcuts to help with this. <Ctrl>+T toggles whether the molecule is displayed or not. So, if your molecule has inexplicably disappeared, it's always worth pressing this key combination...

The program output of Olex2 happens 'behind' the molecule. The wisdom of doing things this way can be debated, but it means that there are fewer windows cluttering your screen. It is possible to adjust the number of lines of output you see by typing:

>>lines n

(e.g. lines 5) to see only 5 lines of the output a time, it may be confusing for procedures producing more that 5 lines (like calcvoid). If you want to see all lines, type:

>>lines -1

Alternatively, you can type 'text' in the console (or use corresponding GUI links) to view the text output in an external text editor. You can always use PgUp and PgDn keys to scroll the console output. There is a limited buffer to hold the console output, however a full transcript of the Olex2 session is available in the log file, which can be displayed using:

>>log

command.

3.11. 控制操纵台和图形可见性

Olex2有一个用于键入指令的内置控制台。有时只希望看到文本(输出)或结构。有数个指令和快捷方式可以实现这一点。Ctrl+T切换显示分子与否。因此，若你的分子莫名其妙地消失了，总是值得试试按下这个组合键……

Olex2的程序输出显示在分子'后面'。用这种方式做事是否明智值得商榷，但这意味着屏幕上乱七八糟的窗口少了。若要调整你所看到的输出文本行数，你可以通过键入：

>>lines n

(例如lines 5)一次只能看到5行输出内容，对于产生超过5行的过程(如calcvoid)，如果你想查看所有行数，请键入：

>>linse -1

或者，你可以在控制台键入'text'(或使用相应的GUI链接)以在外部文本编辑器中查看文本输出内容。你可以始终使用PageUp和PageDown键用于上下滚动控制台输出内容。有一个有限的缓冲区来保持控制台输出，但Olex2会话的完整副本保存于日志文件，该文件的显示可以键入：

>>log

指令。
