x64dbg热键设置的bug（寻源码修改的高人）
本帖最后由 冥界3大法王 于 2021-11-21 11:49 编辑比如你打开x64dbg，找到：选项=》快捷键=》搜索“设置硬件断点（执行）”
并设置一个热键为：Ctrl+Shift+3
但它显示的却是: Ctrl+Shift+#
然后到CPU窗口（上边的）你去按键吧，按到死，它也没有作用
为啥呢？ 因为这是一个bug
不信，你修改 x64dbg.ini 来手动修改为 ：Ctrl+Shift+3就正常了。
如果是Ctrl+Alt+3就正常
Ctrl+3也正常
这是为啥呢？ 原因通过对比试验，很容易猜到 Shift键的处理上没有搞好。
下面是源码：

你用的是字母上面的数字键吗，要不试试数字键盘那边的数字键？ xiaolong23330 发表于 2021-11-21 11:57

那样则显示的是Ctrl+PageDown{:301_976:} 何故 发表于 2021-11-21 12:04
无语，小键盘地球是PageDown啊哈哈哈哈哈
把小键盘Num灯关掉：
则是：Ctrl+Shift+PgDown 这个有趣，shift+3是#，把ctrl+shift+3，按下，电脑说:后面的shift+3怎么翻译?它懵逼了… shift+3就是#，可能当时开发赶时间的时候没有考虑得那么详细，没有进一步考虑和判断
