I've been looking around for others with these problem but haven't found anything so far, much less a fix. The subject line sums up the problems. Cntr-F isn't working in a few apps I use a lot. I think there are others but the main ones are Google Chrome (Version 57.0.2987.98 (64-bit)) and the Arduino IDE (v 1.8.0). I'm running a recent install of Arch Linux and Xmonad 0.13-1 from the Arch repository. I don't have a complex xmonad.hs but I'll post it here. There are a few other glitches like the fact that the menus in the Arduino IDE appear off to the side from the menu labels but I can live with that. Being able to search is kind of important though. What I do right now in both Chrome and Arduino IDE is click on the file menu and then select "Find" from the drop-down menu. It's workable but quite cumbersome. My Haskell skills are actually pretty good BTW so I'm not afraid of the code. I'd even be willing to contribute at some point. import XMonad import XMonad.Hooks.DynamicLog import XMonad.Hooks.ManageDocks import XMonad.Util.Run(spawnPipe) import XMonad.Util.EZConfig(additionalKeys) import System.IO main = do xmproc <- spawnPipe "/usr/bin/xmobar -d /home/gregory/.xmobarrc" xmonad $ docks defaultConfig -- xmonad $ defaultConfig { manageHook = manageDocks <+> manageHook defaultConfig , layoutHook = avoidStruts $ layoutHook defaultConfig , logHook = dynamicLogWithPP xmobarPP { ppOutput = hPutStrLn xmproc , ppTitle = xmobarColor "green" "" . shorten 50 } , modMask = mod4Mask -- Rebind Mod to the Windows key , terminal = "urxvt" }
