Can anyone help me solve this problem: Normally I use shift + command to scale my objects proportional but now its not working anymore.... I already restarted my mac and indesign.... can anyone help me?
Sometines modifier keys are "stolen" by other applications or browser extensions (e.g., anti-virus apps and others).
To test, quit InDesign and restart your computer. If possible, disable startup applications. OPEN INDESIGN FIRST. Test the modifier keys which are not working. If they work now, carefully reload your other applications and see if loading one causes the modifer keys not to work. That will identify the culprit.
