某些组合键不适用于用户应用程序

2024-5-28 • tag-icon

我正在使用 GUI 文本编辑器 SciTE，并且我想使用以下组合键来选择 SciTE 中的矩形文本区域：AltShiftUp和AltShiftDown。

看来我可以在 Linux Mint 中做到这一点，但我无法让它在 Debian 中工作。
Debian 阻止了这些密钥。
我想知道如何使这些密钥可供用户应用程序使用。

我的系统：

Linux Mint 18，MATE 1.14.1
Debian 8.7（杰西），MATE 1.8.1

我用于AltShift在我的两个系统上切换键盘布局（英语-俄语）。
我希望它保持这种状态（因为我的“手指记忆”）。

我尝试过的：
我打开dconf-editor并更改了mouse-button-modifier从<Alt>到的所有位置<Super>，并禁用了所有组合键，然后重新启动了 Linux。
那并没有解决我的问题。

有趣的细节：
当我使用 VirtualBox（主机 = Debian，来宾 = Linux Mint）时，Alt-Shift-Up/Down组合键在来宾系统内工作！

如您所见，AltShift组合键的处理方式有所不同：

在 Debian 键盘布局上，按 PRESS 键打开，
在 Linux Mint 上，键盘布局是通过 RELEASE 键切换的。

顺序：

ALT pressed
SHIFT pressed
(at this moment Debian switches layout)
SHIFT released
(at this moment Linux Mint switches layout)
ALT released

AltShiftUp可能这就是为什么在 Debian 上不起作用的原因。

我如何才能AltShiftUp与AltShiftDebian 共存？
