问题描述
我刚刚从OSX终端切换到iTerm2，并且似乎失去了一项功能.在Terminal中，由于安装了 MouseTerm 滚动浏览less命令的输出. >.
I just switched from OSX Terminal to iTerm2, and I seem to have lost one piece of functionality.In Terminal, I could scroll through output of the less command with my mouse, because I had installed MouseTerm.
但是，当我尝试滚动iTerm2中的less输出时，窗口的滚动条会移动.奇怪的是，滚动与vim一样工作.
However, when I try scrolling less output in iTerm2, the window's scrollbar moves instead.Strangely, scrolling works as expected with vim.
如何在iTerm2中用鼠标滚动less输出?
How can I scroll less output with my mouse in iTerm2?
推荐答案
iTerm2问题现已标记为已修复"-但解决方法是添加一个隐藏选项，因此它不是立即显而易见的如何启用新的AlternateMouseScroll选项.
The iTerm2 issue is now marked as "fixed" -but the fix is to add a hidden option, so it is not immediately obvioushow to enable the new AlternateMouseScroll option.
由Filippo Valsorda(补丁作者)写，一旦安装了iTerm2的夜间版本(在1.0.0.20140629中仍然不存在)，只需运行以下命令:
As Filippo Valsorda (author of the patch) writes,once you install a nightly build (still not present in 1.0.0.20140629) of iTerm2,just run this command:
$ defaults write com.googlecode.iterm2 AlternateMouseScroll -bool true
重新启动iTerm2，您所有的窗口都会报告滚动事件，作为向上/向下箭头转义键当终端处于备用屏幕"(直接寻址)模式时由less，vim，emacs等程序使用.
restart iTerm2, and all your windows will report scroll events as up/down arrow-key escapeswhen the terminal is in the "alternate screen" (direct addressing) modeused by programs like less, vim, emacs, etcetera.
对于诸如vim和emacs之类的提供附加鼠标支持的应用程序，您仍然需要启用鼠标报告模式，因为此自动模式开关只能启用滚动.
For applications like vim and emacs that provide additional mouse support,you will still want to enable mouse reporting mode,as this automatic mode switch only enables scrolling.
