manjaro本地安装软件后添加快速启动到开始菜单

以pycharm举例
1 首先安装软件，例如安装到 /usr/local/src/pycharm-2018.2.7
2 在 /home/用户名/.local/share/applications 文件夹下新建 jetbrains-pycharm.desktop
3 jetbrains-pycharm.desktop 内容如下

[Desktop Entry]
Version=1.0
Type=Application
Name=IntelliJ PyCharm Professional
Icon=/usr/local/src/pycharm-2018.2.7/bin/pycharm.png
Exec="/usr/local/src/pycharm-2018.2.7/bin/pycharm.sh" %f
Comment=Capable and Ergonomic IDE for JVM
Categories=Development;IDE;
Terminal=false
StartupWMClass=jetbrains-pycharm

添加后，在开始菜单，也就是 application finder 中就能找到对应软件的快速启动按钮啦
