Comment assigned Ctrl+H, since no hotkey was assigned and it mirrors Hide functions(but H doesn't work in a text editor as a hotkey). A common shortcut for this is Ctrl + / but this doesn't work on non English keyboards(Ctrl + Shift + 7(=Ctrl + /) doesn't work in Blender)
Uncomment assigned Alt+H, since it mirrors Show Hidden Objects/Unhide.
Replace assigned Ctrl+R, since Ctrl + H was previously assigned to Replace, and Ctrl + R is standard in ex. pycharm for replace.
Find Set Selected Alt + F, since no hotkey was assigned and this is a useful function with a hotkey.
As far as I can see, will these changes not cause any changes in the current Text Editor manual: https://docs.blender.org/manual/en/dev/editors/text_editor.html
