alttab [-w N] [-d N] [-sc N] [`-mk` <str>] [`-kk` <str>] [`-bk` <str>]
[`-pk` <str>] [`-nk` <str>] [`-mm` <N>] [`-bm` <N>] [-t NxM] [-i NxM]
[-vp str] [-p str] [-s N] [-theme name] [-bg color] [-fg color]

(see man page for details)
Unlike task switchers integrated in most simple window managers (WM) or dmenu-like switchers, alttab features visual interface and convenient tactile behaviour: press modifier (Alt) - multiple switch with a key (Tab) - release modifier. Also, it's lightweight and depends only on basic X11 libs, conforming to the usage of lightweight WM.
git clone https://github.com/sagb/alttab.git
cd alttab
./configure && sudo make install
See INSTALL.md for details and doc/wm-setup.md for window manager settings.
Usually it should run fully functional without any argument: alttab.
no-wm: use X11 without a window manager
