问题描述
我不知道我不小心单击了什么热键，但是此«¶外观符号出现在代码的每一行上，并且代码中有灰点而不是空格.
I don't know what the hotkey I accidentally clicked, but this Ǧ looking sign appeared on every line of code, and there are grey dots instead of spaces in the code.
如何摆脱这些字符?
推荐答案
假定这是SQL Developer，请转到工具"->首选项"(或在Mac上，在"SQL Developer"菜单下找到该首选项).展开代码编辑器"部分，然后单击显示".取消选中显示空白字符"(列表中的第二个复选框).
Assuming this is SQL Developer, go to Tools->Preferences (or on Mac, find that under the SQL Developer menu). Expand the Code Editor section and click on Display. Untick "Show whitespace characters" (second checkbox in the list).
您可以在快捷键"部分的首选项"下检查定义的快捷方式.在Mac上，没有这个选项，但是Windows将它作为 + + 来使用，如果您不想浏览首选项窗格.
You can check for defined shortcuts under Preferences, in the Shortcut Keys section. On Mac there isn't one for this, but Windows has it as ++, which will also toggle them off if you don't want to go through the preference pane.
